Ring control needle color does not always update properly

[tgeorge17]

I have a ring control that I am trying to programmatically change needle color on.  A separate control makes the needle transparent, and my intent is that clicking anywhere on the ring control will return the needle color to red. I have this set up through an "EVENT_LEFT_CLICK_UP". However, the only time that the needle color actually changes is when you click on the outside edge of the control. Sample project showing the behavior is attached. Any advice?
