How to detect a route change on foreign Ember application?

I'm trying to make a Chrome extension for Zendesk and it appears that their application is built with Ember. I used $(document).ready, but that is only really firing if I refresh the pages... otherwise it doesn't fire at all. How can I listen for page changes in Zendesk for my Chrome extension?

I looked around and only found answers that would help only if it was my own Ember app. Also, it isn't a hashchange.
