Linking to RJS files from multiple locations

Hi,
I have a simple RJS file which adds some text to a div like so....

VIEW

  <%= button_to_remote "Test", :url => {:action => 'test'} %>

RJS

page.insert_html :bottom, "testdiv", "test value"

This works fine, however I'd like to place the RJS file in a different
directory and use it with multiple controllers.

<%= button_to_remote "Test", :url => {:controller => 'testcontroller',
:action => 'test'} %>

The RJS file is the same, just moved to the 'testcontroller' view
directory. This dosen't seem to be working, can anyone advise me as to
what's going wrong?
Thanks.

Is the request even reaching the testcontroller?
