Not really, the checked value that is bound is a computed property that checks whether the underlying permalinks value is just `/:slug/` or not.  I cannot figure out how to fire an action or event handler when the checkbox is clicked also.

I even tried to make a new custom checkbox view, and do it that way but had no luck.  We are doing something funky with labels over that checkbox to style it and it's not playing nice with the "Ember way".
