callbacks renamed layer

I had this dialog

(
	global test
	rollout test "Untitled" width:162 height:48
	(
		dropDownList ddl_Laylist "DropDownList" pos:[5,3] width:154 height:40
		
		fn MyContainedLayer =
		(
		ddl_Laylist.items=#()
		layerContent= #("0 (default)") + sort (for layer = 1 to layerManager.count - 1 collect (layerManager.getLayer layer).name)
		ddl_Laylist.items=layerContent
		)
		
		on test open do
		(
			MyContainedLayer()
			callbacks.removeScripts  id:#lay_List03	
			callbacks.addScript #layerCreated "test.MyContainedLayer()" id:#lay_List03	
			callbacks.addScript #layerDeleted "test.MyContainedLayer()" id:#lay_List03	
			callbacks.addScript #nodeLayerChanged "test.MyContainedLayer()" id:#lay_List03	
		)
	)
	createdialog test
)

the callbacks layer created n layer deleted is workin fine but when I try to rename the layer from layer manager, its seems not update in my ddl_laylist items as well, but i already add node layer changed callbacks, did something wrong with my script !? please I need some suggestion to make my script working.

Thanks

best regard
