symfony2 custom annotation translation - symfony

Question

Please help me to translate custom annotation.
I'm trying to translate #Render(title="Page"). Translate generator not found this, and title not traslate.
I try to understand how it is done in the component validation Symfony but nothing happens.
<?php
namespace Shooos\ProductBundle\Controller\Admin;
use Sensio\Bundle\FrameworkExtraBundle\Configuration as PRS;
use Shooos\CoreBundle\Controller\BaseController;
use Aft\RenderParkingBundle\Annotations as CA;
use Gedmo\Mapping\Annotation\Translatable;
/**
* #PRS\Route("/admin")
* Class CategoryController
* #package Shooos\ProductBundle\Controller\Admin
*/
class CategoryController extends BaseController
{
/**
* #CA\Render(title="Categories")
* #PRS\Route("/categories", name="admin.categories")
*/
public function indexAction()
{
}
}
<?php
namespace Aft\RenderParkingBundle\Annotations\Driver;
use Doctrine\Common\Annotations\Reader;
use Sensio\Bundle\FrameworkExtraBundle\Templating\TemplateGuesser;
use Symfony\Component\HttpKernel\Event\FilterControllerEvent;
use Symfony\Component\HttpKernel\Exception\AccessDeniedHttpException;
use Aft\RenderParkingBundle\Annotations;
use Symfony\Component\Translation\TranslatorInterface;
class AnnotationDriver
{
/**
* #var Reader
*/
private $reader;
/**
* #var TemplateGuesser
*/
private $guesser;
/**
* #var TranslatorInterface
*/
private $translator;
public function __construct(Reader $reader, TemplateGuesser $guesser, TranslatorInterface $translator)
{
$this->reader = $reader;
$this->guesser = $guesser;
$this->translator = $translator;
}
/**
* This event occurs when call any controller
*/
public function onKernelController(FilterControllerEvent $event)
{
/** Controller exists */
if (!is_array($controller = $event->getController())) {
return;
}
/**
* Controller
* #var \ReflectionObject $object
*/
$object = new \ReflectionObject($controller[0]);
$method = $object->getMethod($controller[1]);
foreach ($this->reader->getMethodAnnotations($method) as $configuration) {
if ($configuration instanceof Annotations\Render) {
$request = $event->getRequest();
$title = $this->translator->trans($configuration->getTitle());
$request->attributes->set('_page_title', $title);
if (null === $configuration->getTemplate()) {
$configuration->setTemplate(
$this->guesser->guessTemplateName(
$controller,
$request
));
}
$request->attributes->set('_page_template', $configuration->getTemplate());
}
}
}
}

On your annotation to object converter, where you inject the annotation reader, inject the translator service and translate the value at the transformation process, from annotation to object.
$description = $this->translator->trans($transformedAnnotationObject->getDescription());
