Set (other) fielf mandatory from ftl template

[wadsok]

Is it possible to set other form field mandatory from JS in ftl template like:

      function updateChanges${field.name?substring(5)}() {
          window.alert("function started");
          var propertyList = ("${field.control.params.filteredProperty}").split(",");
          document.getElementById("${args.htmlid}_prop_" + propertyList[0]).mandatory= false;
         return false;
      }
This one doesn't work, but function gets called.

You can use :
mandatory: ${field.mandatory?string}
