Dynamic Option Ajax Phalcon

sorry for my bad english before.

I have problem when display dynamic value on multiple select using Ajax. Actually on view retrieve the data from controller, but list item on multiple select not change as the data from controller

Controller createAction()

public function createAction(){
    $form = new liistTopicForm(null);
    if ($this->request->isPost()) {
        $post = $_POST;
        $_POST['speciality[]'] = isset($_POST['speciality']) ? $_POST['speciality'] : null;
        $_POST['topic[]'] = isset($_POST['topic']) ? $_POST['topic'] : null;
        $_POST['type[]'] = isset($_POST['type']) ? $_POST['type'] : null;
        unset($_POST['type']);

        if (false == $form->isValid(\array_merge($_POST, $_FILES))) {
            $this->flash->error($form->getSummary());
        } else {
            $ins = new liistTopic();
            $ins->assign($_POST);

            Utility::getAdditionalProperty($_POST, $ins);

            if (true == $this->request->hasFiles()) {
                Utility::getFile($_FILES, $ins);
            }

            if (!$ins->createUsingTransaction()) {
                $this->flash->error($ins->getMessages());
            }

            $this->setTypeMsg($post,$ins);
            $this->flashSession->success('Created');
            $this->response->redirect('cats/'.$this->router->getControllerName());
            $this->view->disable();

            return;
        }
    }
    $this->view->form = $form;
}

Controller catListAction():

public function catListAction()
    {
        $this->view->disable();

        $this->jsonMessages = Schedule::getList($_POST['start']);

        return $this->jsonMessages;
    }

liistTopicForm() :

public function initialize($entity = null, $options = null)
{
    [
        'required' => $required,
        'numeric' => $numeric,
        'url' => $url,
        'file' => $file,
        'empty_file' => $empty_file,
        'date' => $date,
    ] = Form::Validators();

    $file = (isset($options['edit']) && $options['edit']) ? $empty_file : $file;

    //** name **//
    $this->add(Form::Text('name', [], [$required]));
    $this->add(Form::Text('start', [], [$required, $date]));
    $this->add(Form::Text('end', [], [$required, $date]));
    $this->add(Form::Select('tyoe[]', [ 'multiple' => true, 'label' => 'type', 'placeholder' => 'Type', 'id' => 'type' ], [$required], [
        "1" => "Type 1",
        "2" => "Type 2",
        "3" => "Type 3"
    ]));
    $list = Schedule::getList();
    $list[0] = 'All Topic';
    $this->add(Form::Select('topic[]', [ 'multiple' => true, 'label' => 'topic', 'placeholder' => 'Topic', 'id' => 'topic' ], [], $list));
    $list_p = Specs::getList();
    $list_p[0] = 'All Specs';
    $this->add(Form::Select('speciality[]', [ 'multiple' => true, 'label' => 'speciality', 'placeholder' => 'Select speciality', 'id' => 'speciality' ], [], $list_p));
    $this->add(Form::Image('attachment', [], [$file]));
    $this->add(Form::Hidden('_crop', ['value' => '{}'], []));
}

View create.volt:

<div class="card">
  {{ content() }}
  <div class="card-body">
    {{ form('method': 'post', 'autocomplete': 'off', 'enctype': 'multipart/form-data') }}
    {% for element in form %}
      {% if is_a(element, 'Phalcon\Forms\Element\Hidden') %}
        {{ element }}
      {% else %}
        {{ form.render(element.getName()) }}
      {% endif %}
    {% endfor %}
    <div class="form-group">
      <div class="row">
        <label class="col-sm-2"></label>
        <div class="col-sm-10">
          {{ submit_button("Save", "class": "btn btn-fill btn-primary") }}
        </div>
      </div>
    </div>
    </form>
  </div>
</div>

<script type="text/javascript">
  var date = new Date();
    date.setDate(date.getDate() + 1);
$(function() {

  $('#topic').parent().parent().hide();
  $('#speciality').parent().parent().hide();

  icons = {
    time: 'fa fa-clock-o',
    date: 'fa fa-calendar',
    up: 'fa fa-chevron-up',

    today: 'fa fa-screenshot',
    clear: 'fa fa-trash',

  $("#start").datetimepicker({
    minDate: date,
    format: 'YYYY-MM-DD',
    icons,
  });
  $("#end").datetimepicker({
    minDate: date,
    format: 'YYYY-MM-DD',
    icons,
  });

  $("#type").change(function () {

    var value_start = $('#start').val();
    var value_end = $('#end').val();

      $("#type option:selected").each(function () {
          var value_type = $(this).val();
          var data_selected = $('#type').val();

          if(value_type == 2)
          {
            $('#topic').parent().parent().show();

            $.ajax({

          }

          if(data_selected.indexOf("2") == -1)
          {
            $('#topic').parent().parent().hide();
          }
          else if(data_selected.indexOf("3") == -1)

          }
      });

      $("#type ")
  }).trigger("change");
});
</script>

ControllerBase:

public function afterExecuteRoute()
{
    if($this->request->isAjax() == true) {
        $data = $this->dispatcher->getReturnedValue();
        $this->response->setJsonContent($data);
        return $this->response->send();
    }

    $this->view->setViewsDir($this->view->getViewsDir().'cats/');
}

actually ajax retrieve data from catListAction and success, but the list item option on topic not change. Is there something wrong in my script? NOTE : the result should be (just Topic 3) but in fact showed on Schedule::getList() result
