touch.phase == TouchPhase.Canceled not worked

i m tired to handle and solve issues related to multitouch. i m use maximume 5 touch simultaneously but when two touches are down on two object and i moved my fingures then that both touches fired TouchPhase.Ended event but not fired TouchedPhase.Canceled.

I want to fired TouchPhase.Canceled when i my fingures out of those objects.

if (touch.phase == TouchPhase.Began) { hitObject.GetComponent ().TouchDown (hitObject); }

if (touch.phase == TouchPhase.Ended) { hitObject.GetComponent ().TouchExit (hitObject); }

if (touch.phase == TouchPhase.Moved || touch.phase == TouchPhase.Stationary) { hitObject.GetComponent ().TouchStay (hitObject); }

if (touch.phase == TouchPhase.Canceled) { print ("Touched canceled...."); hitObject.GetComponent ().TouchExit (hitObject); }
