calling to a specfic controler

if the create action isn't on the same controller as the create action, you need to specify it, ie
  :url => { :action => "create", :controller => 'some_other_controller' }

To be quite honest, I'm not sure why you've put these in different controllers. That said you can do stuff like render :template => 'some_controller/some_action'
