Why rotation via AddActorLocalRotation does not work

Development Character & Animation

I have class AMyCharacter that inherits ACharacter. I added custom bindings to InputComponent to “Turn” action.
When I try to rotate Actor using

void AMyCharacter::OnTurn(float val) {
	FRotator rot(0, 10*val, 0);
	this->AddActorLocalRotation(rot);
}

it does not work.

But this works:

   AddControllerYawInput(val);

What is the problem with AddActorLocalRotation?
