Internationalization. Call a Action Controller from javascript and ajax.

Hi folks. I’am building a Little aplications with internationalization.

First, I have the files with the string /messaje/es.php, ca.php, en.php

Second, also I have in the ControllerBase this functions

<?php
// *************************************
// Afetgit per a l'internacionalització

protected function _getTransPath()
{
    $translationPath = '../app/mensajes/';
    $language = $this->session->get("language");
    if (!$language) {
        $this->session->set("language", "es");
    }
    if ($language === 'es' || $language === 'ca' || $language === 'en') {
        return $translationPath.$language;
    } else {
        return $translationPath.'es';
    }
}

public function loadMainTrans()
{
    $translationPath = $this->_getTransPath();
    require $translationPath.".php";
    //Return a translation object
    $mainTranslate = new Phalcon\Translate\Adapter\NativeArray(array("content" => $mensajes));
    //Set $mt as main translation object
    $this->view->setVar("mt", $mainTranslate);
}

 //public function setLanguageAction($language='')     Per quees crdat des de index.volt event del onchange del select i cride al Controller amb un ajax
public function setLanguageAction()
    {
        $this->flash->success("Entro");
        if ($this->request->isPost() && $this->request->isAjax()) {
            $this->flash->success("Entro");
        };
        $languaje = $request->getPost('paramLlengua');
        //Change the language, reload translations if needed
        if ($language === 'es' || $language === 'ca' || $language === 'en') {
            $this->session->set('language', $language);
            $this->loadMainTrans();
        }
        //Go to the last place
        $referer = $this->request->getHTTPReferer();
        if (strpos($referer, $this->request->getHttpHost()."/")!==false) {
            return $this->response->setHeader("Location", $referer);
        } else {
            return $this->dispatcher->forward(array('controller' => 'index', 'action' => 'index'));
        }
    }
// **************************************

After, I have in the view index.volt a select for select the lenguaje that the user need, with the event onchange where exists a call for javascript “callActvSetLanguaje(this)”.

                            <!-- Per al select dels idiomes -->
                            <ul class="navbar-right margenTop">
                                <!--<select id="llengua" class="selectpicker form-control colorDesplegableSelect" data-style="btn-primary">-->
                                <select id="llengua" class="selectpicker" data-style="btn-primary" onchange="callSActvSetLanguaje(this)">
                                    <option>
                                        <?php
                                            $msg =  $mt->_("Castella");
                                            echo $msg;
                                        ?>
                                    </option>
                                  <option>
                                        <?php
                                            $msg =  $mt->_("Angles");
                                            echo $msg;
                                        ?>
                                  </option>
                                  <option>
                                        <?php
                                            $msg =  $mt->_("Catala");
                                            echo $msg;
                                        ?>
                                  </option>
                                </select>
                            </ul>    

And finally, the javascript function is the next, where I’m calling the action controller setLanguaje with Ajax.

<script>
            function callSActvSetLanguaje(selectObject){
                var value = selectObject.value; 
                switch(value){
                    case 'Català':
                        llengua = 'ca';
                        break;
                    case 'Castellano':
                        llengua = 'es';
                        break;
                    case 'English':
                        llengua = 'en';
                        break;
                    default:
                        llengua = 'es';
                }
                $.ajax({
                    url: '/ControllerBase/setLanguage',
                    type: 'POST',
                    data: llengua,
                    dataType: 'text',
                    success: function(data){}
                });
            }
        </script>

But, the internationalization not is executed.

Can you see where is the fail? I think that the fail is in the Ajax call!!.

Happy weekend!!!!!
