Manipulator Change and Editing Logic working together

I'm working on a feature with manipulators to change some values, and I also want editing logic to change some values when others are changed. I've got them both working independently, but I'm not sure the best way to make them work together. Put another way, my editing logic works when I type a new value, but not when I change the same value by dragging a manipulator. Is there a way to get it working without somewhat re-creating the editing logic code inside the manipulator change function? Whats an efficient way to do this?

edit: If you see this question twice, you're not crazy. I asked this again in the Using Onshape > FeatureScript section because it seemed like a better spot for it, and was going to delete this one, but now I'm not sure that I can.
