Can I redirect a javascript request to another javascript action?

Question

I have a comment controller with an index and create actions among others. Both of these actions correspond to the html and js formats.

Whenever I get a create request via ajax, I would like to add a new comment and then redirect to index.js, so the comments on the screen are updated without reloading the page.

A similar thing works in Chrome. But whenever I try to do this in Firefox or IE, it turns out that the redirect from create.js gets into index.html ...

Even when I force js redirect:

redirect_to polymorphic_path([@commentable, :comments]), :format => 'js'

It gets into the .html format in Firefox and IE.

Any idea what could be happening here?
