Symfony2 - Sonata Admin - add javascript before field

Question

In admin class:

protected function configureFormFields(FormMapper $formMapper) {
    $formMapper
            ->add('name', 'text')
            ->add('description', 'text')
    ;
}

I don't know how I can before "name" add javascript, can you help me?

Working for me:

In admin class src\PP\TestBundle\TestAdmin.php

public function configure() {
    $this->setTemplate('edit', 'PPTestBundle:CRUD:edit_javascript.html.twig');
}

In src\PP\TestBundle\Resources\views\edit_javascript.html.twig

{% extends 'SonataAdminBundle:CRUD:base_edit.html.twig' %}
{% block javascripts %}
{{ parent() }}
<script src="{{ asset('bundles/pptest/admin/js/myscripts.js') }}" type="text/javascript"></script>
{% endblock %}

When you do all this stuff and you have upload myscripts.js you should send this in command line:

app/console assets:install web

(possible that I forgot something)
