Unreal Engine 4, AddDynamic is not working if being called from constructor

I'm a begginer, trying to finish a simple UE4 C++ tutorial: https://www.raywenderlich.com/185-unreal-engine-4-c-tutorial#toc-anchor-001 At the point where you're additing OnActorBeginOverlap.AddDynamic(this, &ABaseCoin::OnOverlap) into ABaseCoin constructor in order to handle the event, it's just not working. the OnOverlap function is not being called when I overlap this actor( But if I put OnActorBeginOverlap.AddDynamic into ABaseCoin::BeginPlay everything is working. Please, help, who knows something about this problem

Problems arise when using .AddDynamic in the constructor now. It can also cause Blueprint corruption.

Put every constructor .AddDynamic in PostInitializeComponents() or BeginPlay()
