Symfony - Form is not submit - forms

Question

I work with Symfony to build and send a contact form by mail.
I use swiftMailer.
The problem is that my form is not submitted.
So, my swiftmailer can't work because the isSumbitted will stay at false and $mailer->send(message) will not be activate
My controller :
public function index (Request $request, Swift_Mailer $mailer)
{
$form = $this->createForm(ContactType::class);
$form->handleRequest($request);
if($form->isSubmitted() && $form->isValid()) {
$contactData = $form->getData();
$name = $contactData['name'];
$content = $contactData['message'];
$email = $contactData['email'];
$entreprise = $contactData['entreprise'];
$zip = $contactData['zip'];
$message = (new Swift_Message('Vous avez un nouveau message sur le site AMC Industrie.fr'))
->setFrom('test#example.com')
->setTo('test#gmail.com')
->setSubject('Demande d\'information')
->setCharset('utf-8')
->setContentType('text/html')
->setBody(
"
<p> Vous avez reçu un message de <strong>$name</strong>, de l'entreprise <strong>$entreprise</strong>
<br>(code postal : $zip ) <br>
Son email est : <strong>$email</strong>. </p>
<p> Son message :</p>
<p>$content
</p>
"
)
;
$mailer->send($message);
return $this->redirectToRoute('map_contact');
}
return $this->render('contact/map_contact.html.twig', [
'form' => $form->createView()
]);
}
My Form :
{
$builder
->add('name',TextType::class,
['label'=>false,
'constraints' => new NotBlank,
'attr' => [
'class'=> 'form-control',
'placeholder' => 'Nom et prénom',
]
])
->add('email',EmailType::class,
['label'=>false,
'constraints' => new NotBlank,
'attr' => [
'class' => 'form-control',
'placeholder' => 'adresse e-mail'
]
])
->add('entreprise',TextType::class,
['label'=>false,
'constraints' => new NotBlank,
'attr' => [
'class'=> 'form-control',
'placeholder' => 'Nom de votre entreprise'
]
])
->add('zip',NumberType::class,
['label'=>false,
'constraints' => new NotBlank,
'attr' => [
'class'=> 'form-control',
'placeholder' => 'Code postal'
]
])
->add('message',TextareaType::class,
['label'=>false,
'constraints' => new NotBlank,
'attr' => [
'class'=> 'form-control',
'placeholder' => 'Décrivez-nous votre projet'
]
])
->add('save', SubmitType::class,
['label' => 'Envoyer',
'attr'=> [
//'class' => 'waves-effect waves-light btn-large btn btn-primary mt-1 mb-5 lift',
'id' => 'form-submit'
]])
;
}
My template :
<form>
{{ form_start(form) }}
<div class="row">
<div class="col-12 col-md-6">
<div class="form-group mb-5">
{{form_label(form.name, 'Nom et prénom')}}
