I've been struggling with the same issue with UIKit (nice alternative to Bootstrap btw)'s button groups. They work exactly the same way, and get messed up the same way.
I had figured out the same solution, except that I was directly instantiating the CollectionView with .create() (as shown in http://emberjs.com/api/classes/Ember.CollectionView.html).
Though this (sometimes) works, it didn't this time, and replacing .create() with .extend() fixed it. Thanks!
