Symfony 3.1 Post to Web Api - php

Question

I'm trying to make a web API with Symfony but the POST method is not working. My code does not give any error.
Entity/Status:
<?php
namespace RestBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
/**
*
*
* #ORM\Table(name="status")
* #ORM\Entity
*/
class Status
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer", nullable=false)
* #ORM\Id
* #ORM\GeneratedValue(strategy="IDENTITY")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="nome", type="string", length=100, nullable=true)
*
* #Assert\NotBlank()
*/
private $nome;
}
?>
POST Function (Controller/StatusController):
public function postStatusAction(Request $request)
{
$user = new Status();
$form = $this->createForm(StatusType::class, $user);
$form->handleRequest($request);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($user);
$em->flush();
return $user;
}
//var_dump($form->getErrors());
throw new HttpException(400, "Invalid data");
}
Form/StatusType:
<?php
/**
* Created by PhpStorm.
* Date: 10/08/16
* Time: 10:39
*/
namespace RestBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Form\Extension\Core\Type\TextType;
class StatusType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('nome', TextType::class);
}
/**
* #param OptionsResolver $resolver
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'RestBundle\Entity\Status',
'csrf_protection' => false,
));
}
/**
* #return string
*/
public function getBlockPrefix()
{
return '';
}
}
Thanks.

A controller MUST return a Response :
public function postStatusAction(Request $request)
{
$user = new Status();
$form = $this->createForm(StatusType::class, $user);
$form->handleRequest($request);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($user);
$em->flush();
return new Response($user->getUsername());
}
//var_dump($form->getErrors());
throw new HttpException(400, "Invalid data");
}
