Broadcast message to all child of game object

Hi,
I have created some labels from label factory and made them all child of a particular game object by sending message set_parent to created label components.

Now I am sending disable message to game object , which will be broadcast to its all children.
Should not all labels under it be disable ?
But I can see them on screen.

I have to run for loop to send disable message to each separately and then can see the effect.

Any concept I am wrongly referring.

The messaging system does not support broadcasts to child game objects. A message sent to a game object will be received by all components, not all child game objects.

Thanks for clarification
