How to bind dynamic delegate to multicast dynamic delegate

I have found a solution, and I publish a solution for people who suffer from a similar problem.

You can simply bind the delegate using ‘Add’ fucntion instead of ‘AddDynamic’ :

void AInitManager::SafeRefUniqueToActor(FReferenceDelegate EventToBind)
{
	if (bUniquesEndInit == true)
	{
		EventToBind.ExecuteIfBound();
	}
	else
	{
		// this works correctly
		OnUniquesEndInit.Add(EventToBind);
	}
}
