I want to create a zul page with a label which value is generated by a Javascript file.

I have create the following code but somehow it doesn't work:

<label id="oldest" style="color:#000000;font-size:110px; text-align: center">
         <attribute name="value" >
             <![CDATA[
                 <script language="javascript">
                      function getValue() {
                          return 'Hello JavaScript';
                      }
                 </script>
             ]]>                        
          </attribute>
</label>

Any idea on how to make this thing work? Thanks in advance
