Oculus touch, input for hand models

Hi, I've been trying to "attach" hand models to Oculus touch. So far I was able to do an idle animation and trigger a "grab" animation when you press one of the touch triggers. I defined a button input in the "input" section, and just calling it like this:

animator.SetBool("isGrabbing", Input.GetAxis(buttonName) == 1);

That works. However, I'd like to have "pointing" animation and would like to call this when the index finger is off the touch controller. I've looked at the Oculus...
