Why is OnClicked not firing when I click my object?

I wish that were the case, but i believe i have it set already.

This may help though: I can get a click event to fire for my tree. And the tree has a 'Collision section in the details, whereas my buttons (which are copies of the Commentary_Box from the Blueprints Example Demo minus the little i symbol) and the box brush do not have these settings in the details window.
