Don’t see anything wrong with that specifically and its not giving you any errors… my old project is also having same issue… 
Found a quick solution though. You could implement this and run the function there: AActor::OnConstruction | Unreal Engine Documentation
Tested and it works.
From Actor.h:
/**
* Called when an instance of this class is placed (in editor) or spawned.
* @param Transform The transform the actor was constructed at.
*/
virtual void OnConstruction(const FTransform& Transform) {}
