I'm trying to call a method within my model element upon a button click. Here's my code

<listbox model="${$composer.model2}" >
            <template name="model">
                <listitem>
                    <listcell label="${each.getName()}">
                        <button onClick="${each.toggeSort()};"/>
                    </listcell>
                </listitem>
            </template>
        </listbox>

onClick="${each.toggeSort()}; is not the right way to do it. How should this be done?

if you insist on doing it inside the zul file (using interpreted beanshell, PERFORMANCE IMPACT) just do this <button onClick="each.toggeSort();"/>, for better performance use the listener approach explained by Darksu

@cor3000, using onClick="each.toggeSort();" throws error 'undefined variable or class name: each'

I'll get back when I have more time

sorry for missing a little step, here a running example: http://zkfiddle.org/sample/2q2qofp/1-call-method-on-model-item still registering an event listener at the java side is more performant than using inline scripting

Thanks. I'll try to use listener in my composer by forwarding the event to the listbox

Hello Dhanasiddharth,

My personal opinion is that you should use a renderer:

http://books.zkoss.org/wiki/ZK%20Developer's%20Reference/MVC/View/Renderer/Listbox%20Renderer

And a renderer example:

        public void render(Listitem listitem, Object obj, int index) throws Exception {

            //Initialize Object
            final MyObject myObject = (MyObject) obj;
            listitem.appendChild(new Listcell(myObject.getXXX()));

            //Add onClick record event
            listitem.addEventListener("onClick", new EventListener()
            {
              public void onEvent(Event event)throws Exception
               {

               }
            });
        }

Best Regards,

Darksu
