switch to init() hook => afterRender
switch to init() hook => afterRender

I was getting the following deprecation message:

> DEPRECATION: A property of <dummy@view:-outlet::ember362> was modified inside the didInsertElement hook. You should never change properties on components, services or models during didInsertElement because it causes significant performance degradation. [deprecation id: ember-views.dispatching-modify-property]

In the past I've found that **init() => afterRender** works better in a lot of situations. I'm going to test this now.
