How to add a callback to Character in Bleeding

Hey there,

I have been searching high and low for Bleeding docs for creating a character / character controller,

I've managed to get the character running in the application, but it doesn't collide with static bodies in my world.

I can't find any way to put a physx callback for the kinematic controller.

Any help would be greatly appreciated. I've already looked in the forums, and seen the Physx character + nxogre post.
I'd preferably like to use the bleeding character and add the callback for it with as little physx code as possible.

Thanks.
