How to override the controller?

Question

symfony

I'm trying to change the user registration order to add roles to them automatically.
Unable to override controller.

<?php
namespace ACVote\UsersBundle;
use Symfony\Component\HttpKernel\Bundle\Bundle;
class ACVoteUsersBundle extends Bundle
{
  public function getParent()
    {
        return 'FOSUserBundle';
    }
}

controller code. part of the code omitted.

<?php
namespace ACVote\UsersBundle\Controller;

use FOS\UserBundle\Controller\RegistrationController as BaseController;
use Symfony\Component\HttpFoundation\Request;

class RegistrationController extends BaseController
{
    public function registerAction(Request $request)
    {

        /** @var $formFactory \FOS\UserBundle\Form\Factory\FactoryInterface */
        $formFactory = $this->get('fos_user.registration.form.factory');
        /** @var $userManager \FOS\UserBundle\Model\UserManagerInterface */
        $userManager = $this->get('fos_user.user_manager');
        /** @var $dispatcher \Symfony\Component\EventDispatcher\EventDispatcherInterface */
        $dispatcher = $this->get('event_dispatcher');

        $user = $userManager->createUser();
        $user->setEnabled(true);
        $user->setSuperAdmin(true)
        $user->SetRole(ROLE_SUPER_ADMIN);

        $event = new GetResponseUserEvent($user, $request);

The semicolon is intentionally omitted to show that this code is not being executed at all.
