Player won't move on Touch Input

Hi!

So i am developing a Game for the GearVR. I am trying to make my Character move when the TouchPad of the GearVR is touched. So the Character should just keep on walking as long as my fingers are on the touch pad. As soon as i release the touchpad, the character should just stop walking. The Event of the “Touching” is detected, but for some reason, the “Add Movement Node” just doesn’t seem to react. The Character is simply not moving. Also, in the Input Settings, i cleared the “Default Touch Interface”, so i don’t have these virtual Thumbsticks on my screen.Can somebody please help me?
