I am trying to populate a textbox value on change of a combobox in a mvvm form. Data updates in textbox correctly but validator class getting null value for the textbox field on click of save button. How to rebind the textbox value to vm?

Here is my form code...

<window id="w_add_list" title="Add New Object" position="center,top" border="normal" width="800px" closable="true">
<zscript>

    <style>   
        .error {color:#ff0000; font-size: 11px;}
    </style>

    <div apply="org.zkoss.bind.BindComposer" viewModel="@id('vm') @init('com.qk.or.ORListViewModel')"
        validationMessages="@id('vmsgs')" form="@id('list') @save(vm.newList, before='add') 
        @validator('com.qk.or.ListAddValidator')">
        <grid>
