I created a children binding example with <listhead> and it works as expected. Please check http://zkfiddle.org/sample/6iq8va/2-children-binding

could you provide a runnable example similar to mine? so that we can reproduce your case. You can create such a reproducible example by removing other irrelevant components and simplify the listbox progressively, then you might find the root cause.

so, is your problem solved? since I can't imagine the problem you described without a code example.

if you use a ListModelList to store headers, calling ListModelList API will automatically update the rendering in your browser. If you don't use ListModelList, then you have to @NotifyChange by yourself.
