Override the default view not working

Hi,

I'm having a problem overriding the default view thats being rendered. I have tried using :

$this->view->pick('example');

here is my full code:

config.php

<?php
/*
 * Modified: prepend directory path of current file, because of this file own different ENV under between Apache and command line.
 * NOTE: please remove this comment.
 */
defined('BASE_PATH') || define('BASE_PATH', getenv('BASE_PATH') ?: realpath(dirname(__FILE__) . '/../..'));
defined('APP_PATH') || define('APP_PATH', BASE_PATH . '/app');
return new \Phalcon\Config([
    'database' => [
        'adapter'     => 'Mysql',
        'host'        => 'localhost',
        'username'    => 'root',
        'password'    => '',
        'dbname'      => 'example',
        'charset'     => 'utf8',
    ],
    'application' => [
        'appDir'         => APP_PATH . '/',
        'controllersDir' => APP_PATH . '/controllers/',
        'modelsDir'      => APP_PATH . '/models/',
        'migrationsDir'  => APP_PATH . '/migrations/',
        'viewsDir'       => APP_PATH . '/views/example/',
        'pluginsDir'     => APP_PATH . '/plugins/',
        'libraryDir'     => APP_PATH . '/library/',
        'cacheDir'       => BASE_PATH . '/cache/',
        // This allows the baseUri to be understand project paths that are not in the root directory
        // of the webpspace.  This will break if the public/index.php entry point is moved or
        // possibly if the web server rewrite rules are changed. This can also be set to a static path.
        'baseUri'        => preg_replace('/public([\/\\\\])index.php$/', '', $_SERVER["PHP_SELF"]),
    ]
]);

loader.php

<?php
$loader = new \Phalcon\Loader();
/**
 * We're a registering a set of directories taken from the configuration file
 */
$loader->registerDirs(
    [
        $config->application->controllersDir,
        $config->application->modelsDir

    $url = new UrlResolver();

    return $url;

    if ($config->database->adapter == 'Postgresql') {
        unset($params['charset']);
    }

    $connection = new $class($params);

    return $connection;
});

/**

/**

 */
$di->setShared('session', function () {
    $session = new SessionAdapter();
    $session->start();

    return $session;

ExampleController.php

<?php

class ExampleController extends ControllerBase
{

    public function indexAction()
    {
      // $result = Test::findFirst([
      //   'columns'    => 'id, name',
      //   'conditions' => 'active = ?1',
      //   'bind'       => [
      //       1=> 1,
      //   ]
      // ])->toArray();
$this->view->pick('example');
    }
}

Currently the ExampleController is still outputting the index.volt file, I would like to output the example.volt file instead. I have tried clearing the cache as well any help with thi would be appreciated.

Thanks
