List Custom addition

Hi,

I've modified the list to have a service that,when triggered, will reset the selected row to null (for the dropdown).

This is mostly what I have in the Runtime JS.

Now the problem is, it does remove the selected value on the dropdown actual value, But when I open the dropdown the value is still selected.

How would I remove the selectedItem from data ?

this.serviceInvoked = function ( serviceName )
{
    var thisWidget = this;
    switch ( serviceName )
    {
         case 'ClearSelectedItem':
              this.resetData();
         break;
         default:
         TW.log.error( 'Folding Panel widget, unexpected serviceName invoked "' + serviceName + '"' );
    }
};
this.resetData = function ()
{
    var thisWidget = this;
    thisWidget.updateSelection( 'Data', [] );
    thisWidget.clearCurrentValueHtml();
    thisWidget.setProperty( 'SelectedText', undefined );
    thisWidget.updateSelection( 'Data', [] );
};
