IndexController handler class cannot be loaded

Good personal day, I have this problem and can not solve it. Instanciei this class, and then used the handle method al complained that could not instantiate, what should I do?

    $id->set('view',function(){
        $view = new \Phalcon\Mvc\View();
        $view->setViewsDir('../app/views/');
        return $view;
    });
    $application = new \Phalcon\Mvc\Application($id);
    echo $application->handle()->getContent();
