Ragdoll demo problem

I'm trying to put ragdoll demo working in Ogre 1.7.0 and OgreNewt2 but for that i will need a little help of community.
When i put this code working i will past it here for everyone.
I need to find the following equivalent functions in OgreNewt2:

- setCustomTransformCallback
- calculateStopAlpha
- setCallbackAccel

Thanks in advance!
