Ember.js and turbolinks does not work well together.
I was using turbolinks and emberjs in a rails 4 app (where turbolinks is included by default) and it was causing errors to me. Especially when I used the browser back button. Turbolinks was causing the page to reload when it was not supposed to, preventing ember to render the template.
