How can I Move Child Components with Transform Widget?

I’m building an actor in C++ which manages a group of procedurally generated chunks for player interaction. Overall I’m not having too many problems, but one thing I can’t seem to figure out is how to get the actor (and its child components) to respond to modifying the actor in editor using the translation/rotation/scaling widgets. I am overriding AActor::PostEditChangeProperty(FPropertyChangedEvent & PropertyChangedEvent) to regenerate the grid, but I still only seem to get triggered generation after editing the translation/rotation/scaling using the ‘Transform’ section of the ‘Details’ panel.

Any help is much appreciated, I assume I have just not figured out the correct way to search for the answer someone else has already provided.
