Chosenbox doesn't send onSelectSubModel direcly to the server using ListSubModel

<zk>
	<zscript>
		ListModelList myModel = new ListModelList(Locale.getAvailableLocales());
		ListModel mySubModel = ListModels.toListSubModel(myModel);
	</zscript>
	<vlayout id="hl">
		<chosenbox id="myCb" style="min-width:75px;" hflex="1"
			creatable="true" model="${mySubModel}"
					onSelect='myLb.setModel(new ListModelList(myModel.getSelection()));' name="chosenboxinput">
		</chosenbox>
		<listbox id="myLb"/>
		<button
			onClick='System.out.println(myModel.getSelection());'>
			getSelection
		</button>
	</vlayout>
</zk>
