Updating the form data in different Controller Action in Symfony - symfony

Question

via EditController I let the user change his item. then I want to handle the update procedure in another Controller (UpdateController). But it does not work! He creates a new Item instead of updating the Item. In UpdateController I used dd (...) I found out that Id and Profile are not being forwarded to UpdateController.
Hopefully you can help me with it.
This is ItemEntity relationship met Profile
/**
* #ORM\ManyToOne(targetEntity="App\Entity\Profile", inversedBy="items")
* #ORM\JoinColumn(nullable=false)
*/
private $profile;
This is ProfileEntity relationship met Items
/**
* #ORM\OneToMany(targetEntity="App\Entity\Items", mappedBy="profile")
*/
private $items;
This is EditController
/**
* #IsGranted("ROLE_USER")
* Class EditController
* #package App\Controller
*/
final class EditController extends AbstractController
{
/**
* #Route("/item/edit/{items}", name="edit_item")
*
* #param Items $items
* #return Response
*/
public function edit(Items $items)
{
$form = $this->createForm(CreateTodoFormType::class, $items, ['action' => $this->generateUrl('update_item')]);
return $this->render('item/edit.html.twig', [
'todoForm' => $form->createView(),
'viewData' => $form->getViewData()
]);
}
}
This is UpdateController
/**
* #IsGranted("ROLE_USER")
* Class UpdateController
* #package App\Controller\Item
*/
final class UpdateController extends AbstractController
{
/**
* #Route("/item/update", name="update_item", methods={"POST"})
*/
public function update(EntityManagerInterface $em, Request $request, TranslatorInterface $translator)
{
$form = $this->createForm(CreateTodoFormType::class);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$item = $form->getData();
$profile = $em->getRepository(Profile::class)->findProfileById($this->getUser()->getId());
$item->setProfile($profile);
$em->persist($item);
$em->flush();
$this->addFlash('success', $translator->trans('The new ToDo is updated.'));
return $this->redirectToRoute('item');
}
return $this->render('item/edit.html.twig', [
'todoForm' => $form->createView(),
]);
}
}
