CreateUser through controller FosUserBundle

Ill try to add some data to database and in the same controlle create user by userManager aswell. Ill made something like this, there is no error nothing when i submit this form which i rendered page just reload and this not even redirecting to route, nothing. Any idea what`s wrong ?

EDITED

My controller look right now like:

/**
     * @Route("/dystrybutor/pracownicy/add", name="dystrybutor_pracownicy_add")
     */

    public function new(Request $request)
    {


    $pracownik = new Pracownik();

    $form = $this->createForm(PracownikType::class, $pracownik);

        return $this->render('dystrybutor_pracownicy/new.html.twig', array(
            'form' => $form->createView(),
        ));



        $form->handleRequest($request);





    if ($form->isSubmitted() && $form->isValid()) {
        $id = $this->getUser()->getDystrybutorId();

        $username = $form["username"]->getData();
        $password = $form["password"]->getData();
        $email = $form["email"]->getData();



        $userManager = $container->get('fos_user.user_manager');
        $user = $userManager->createUser();
        $user->setUsername($username);
        $user->setEmail($email);
        $user->setLocked(0); 
        $user->setEnabled(1); 
        $user->setPlainPassword($password);
        $user->addRole("ROLE_PRACOWNIK");



                try {


            $entityManager = $this->getDoctrine()->getManager();
            $entityManager->persist($user);
            $entityManager->flush();

        } catch (\PDOException $e) {

            $this->get('session')->getFlashBag()->add(
                'error', 'Wystąpił błąd przy udodawaniu użytkownika!'
            );
            return $this->redirect($this->generateUrl('dystrybutor_pracownicy'));

        }  


        return $this->redirectToRoute('dystrybutor_pracownicy');
    }
    }

But still ORM not add user to database, nothing happend. Here what i use in this controller:

use Doctrine\ORM\EntityRepository;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use App\Entity\Dystrybutor;
use App\Entity\Clients;
use App\Entity\Pracownik;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\DateType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Component\Security\Core\User\UserInterface;
use FOS\UserBundle\Model\UserManagerInterface;
use App\Form\PracownikType;
use FOS\UserBundle\Doctrine\UserManager;

And this is how i build my own formType, i am sure the problem is that i not submiting it properly and controller not handle it.

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('username')
        ->add('name')
        ->add('surname')
        ->add('phone')
        ->add('password', RepeatedType::class, array(
                'type' => PasswordType::class,
                'invalid_message' => 'Hasła muszą być takie same.',
                'options' => array('attr' => array('class' => 'password-field')),
                'required' => true,
                'first_options'  => array('label' => 'Hasło'),
                'second_options' => array('label' => 'Powtórz hasło'),
            ))
        ->add('email')
        ->add('save', SubmitType::class, array('label' => 'Dodaj pracownika'));
}

/**
 * @Route("/user/new", name="new_user")
 */
public function addUser(UserManagerInterface $userManager, EntityManagerInterface $entityManager) // use dependency injection as recommended by symfony
{
    $user = $userManager->createUser();

    $user->setPassword('1312adaSz');
    $user->setEmail('eadas@emadi.com');
    $user->setUsername('user6');
    $user->setEnabled(true);
    $user->setRoles(array_merge($user->getRoles(), array_diff(['ROLE_USER', 'ROLE_ADMIN'], $user->getRoles()))); // roles stored as array

    $entityManager->persist($user); // add user to queue
    $entityManager->flush();
