function Leadtools.Controls.InteractiveService.stopListening()
Calling this method will cause the service to unhook from the EventsElement events. The Tap, DoubleTap, Hold, DragStarted, DragDelta, DragCompleted, PinchStarted, PinchDelta and PinchCompleted will not fire after StopListening is called.
The ImageViewer will automatically call StopListening on its instance of InteractiveService when its disposed.
