View settings with securesocial & play 2

I would like to customize securesocial views. I cannot find how to specify the action url for my forms.

When I try:

<form action="@routes.securesocial.controllers.Registration.handleSignUp(token)"
      class="form-horizontal" autocomplete="off" method="POST">

      

        
        
        
      

    

In the route file, I set up the route:

POST    /signup/:token     securesocial.controllers.Registration.handleSignUp(token)

      

        
        
        
      

    

I have an error:

value securesocial is not a member of object controllers.routes

      

        
        
        
      

    

I don't find any samples.

How do I customize the form action? Thanks for any advice.
