Не вижу в диспетчере EventSubscriber

Делаю по мануалу http://symfony.com/doc/current/cookbook/doctrine/event_listeners_subscribers.html

class LifecycleSubscriber implements EventSubscriber
{
    public function postPersist(LifecycleEventArgs $args)
    {
        $this->upload($args);
    }
    public function postUpdate(LifecycleEventArgs $args)
    {
        $this->upload($args);
    }

    public function upload(LifecycleEventArgs $args)
    {
        $entity = $args->getEntity();
        if ($entity instanceof Upload) {
            $entityManager = $args->getEntityManager();
        }
    }
    public function postFlush(PostFlushEventArgs $eventArgs)
    {
        if ($this->needsFlush) {
            $this->needsFlush = false;
            $eventArgs->getEntityManager()->flush();
        }
    }
     public function getSubscribedEvents()
     {
         return array(
             'postPersist',
             'postUpdate',
         );
     }
}

Service:

services:
    cyber.upload.lifecycle.subscriber:
        class: Cyber\UploadBundle\Event\LifecycleSubscriber
        tags:
            - { name: doctrine.event_listener, event: postPersist, connection: default }
            - { name: doctrine.event_listener, event: postUpdate, connection: default }
            - { name: doctrine.event_listener, event: prePersist, connection: default }

В debug:event-dispatcher listener-а нет

Возможно я не правильно пытаюсь использовать и там ничего не должно быть
