Sort dimension by extension?

[#1]

Hello,

how can I sort dynamicly a dimension by an extension?

I define the dimension in definition.xml:

...

<Dimension  Initial=""/>

  <Initiate Name="Chart.Dimension.1.Field" Value="AdvertiserPageNumber" />

...

I tried this code in the extension:

Qva.AddExtension(name, function(){

    var

          me = this,

          $this = $(this.Element),

          $btn = $('<div/>')

                         .text('sort')

                         .click(function(){

                              me.Layout.SetProperty('Chart.Dimension.1.Sort.PrimarySort.Use', '0', false);

                              me.Layout.SetProperty('Chart.Dimension.1.Sort.PrimarySort', '3', false);

                              me.Layout.SetProperty('Chart.Dimension.1.Sort.PrimarySortOrder', '1', true);

          });

     $this.append($btn);

});

If I start the application in the web view and press the button, nothing happends. The annonym function is called and no data is sorted. I hope you can helf me.

Regards
