Zend Forms, subforms and Javascript

[xiarea]

Hi,

I'm building a web app that will have a lot of forms. Most of them have fieldsets in common that I organized in subforms.
I've also made a set of JavaScript functions for each fieldset to automatically fill its fields.

I've made a php file and a js for each subform but I can't get how to dynamically link them.
I'd like the subform file to take care of what js file it needs. Is there a way to do so?
