Ion-nav-view and .animate()

Hello,

I guess everone knows the .animate() function which is implemented in ng-animate.
This function has a .enter() and .leave() for the ui-view.
I try to make a behavior like this example: https://github.com/DevAndyLee/Angular-Hero.
I got this working with ui-view as Angular-Hero hooks in the .enter() and .leave() of the ui-view.
But when I try to do this with ion-nav-view it won’t work.
I thought ion-nav-view was bases on ui-view.

Can someone tell me how I could make it work the Ionic way?
I can’t get it to work…
