How can I send JSON response in symfony2 controller

I am using jQuery to edit my form which is built in Symfony.

I am showing the form in jQuery dialog and then submitting it.

Data is entering correctly in database.

But I don't know whether I need to send some JSON back to jQuery. Actually I am bit confused with JSON thing.

Suppose I have added a row in my table with ``jQuery and when I submit the form then after data is submitted I want to send back those row data so that I can dynamically add the table row to show the data added.

I am confused how can get that data back.

This is my current code:

$editForm = $this->createForm(new StepsType(), $entity);

$request = $this->getRequest();

$editForm->bindRequest($request);

if ($editForm->isValid()) {
    $em->persist($entity);
    $em->flush();

    return $this->render('::success.html.twig');               
}

This is just the template with success message.

If you are using symfony 5 propably it will works.

$data = $serializer->serialize(array('key' => 'value'), JsonEncoder::FORMAT);

return new JsonResponse($data, Response::HTTP_OK, [], true);
