Animating new ion-item in ng-repeat collection

Hi. First of all great work on the framework.

I currently have a ion-list that contains an ion-item with a ng-repeats attribute.

The item is displays as a div with several interactive children (radio buttons).

Depending what the user selects, the a new item is added to the ng-repeat collection and is displayed at the top of the list.
This all works fine.

What I’d like to do is animate this new item with a fade in. I’ve tried a number of things, nothing works.

Any reference implementation on how to accomplish this?
