Is there a way to resolve view model properties as input to client side javascripts?

In the example shown below, the "????" indicates the bit that I have a problem with. The my.zul fragment shows a listbox where the attribute "w:onSelect" defines a client side event which is trigged when an entry in the listbox is selected:

my.zul fragment::

<window id="reportPanelWindow" 
    apply="org.zkoss.bind.BindComposer" 
    viewModel="@id('vm') @init('com.alpha.pineapple.web.zk.viewmodel.ModulePanel')" 
    hflex="1" vflex="1" border="none" >

... layout stuff here....

<listbox id="modelListbox" 
    model="@load(vm.models)" 
    selectedItem="@bind(vm.selectedModel)"
    onSelect="@command('loadSelectedModel')"            
    w:onSelect="helloJS( ????? )"

I would like the event to invoke a JavaScript defined in the zul named "helloJS" to which I need to provide input from the view model as argument.

The two possible solutions that I hope for help with is either:

1) Resolution of view model properties (e.g. vm.xxxx) as input to a java script. As stated above the missing part is illustrated with the ???? in the example above.

2) Access to view model properties from within a java script defined in a ZUL, e.g. can I access the view model vm from the helloJS script?
