Event trigger PointerUp on Mobile (Unity 4.6)

I’m trying to implement a really simple behaviour on a button.
When it get pressed it calls a function passing a bool set as true and when it get released it calls the same function with false.

So I 've just attached an Event Trigger component to the button (Note: This button is part of the new GUI system that comes with Unity 4.6) and I’ve added the PointerDown and PointerUp event.

Here a screenshot of my configuration:

If I try this code within Unity it works… if I build the project for iOS Only the pointerDown event get triggered, the pointerUp is never called. What do you think about that? is there a way to make it works on Mobile … or maybe is it just a bug of the 4.6 b17 version?

I have talked with Unity QA and it seems the mistake I had in my scene was checking a box on my Standalone Input Module that said “Allow Activation on Mobile”. In order for my scene to work properly I had to uncheck that box. Now all of my PointerUps and Downs work.

I was building for Android, not iOS so it may not be the same issue, but it sure sounds similar. I hope that helps!
