Calling WPF Application Function from JavaScript Button

Question

I have a xbap application and i would like a javascript button to call a function from this application. I've read something on Internet and it seems i have to use either a webcontrol (is that correct?) or an object control whom to pass an id or something. How should i do that exactly? A small Vb.Net example would be useful.

Let's assume i have this class:

Class Page1
    Public Sub Callback()
        MsgBox("Something")
    End Sub
End Class

And i have a html file with an iframe that looks like this:

<html>
</head>
<script>
function something() {
               var ctrl = document.getElementById("testControl");
              ctrl.Callback();
           }
</script>
</head>
<body>


    <object id="testControl" name="testControl" classid="clsid: ..." width="0" height="0"></object>
    <input type="button" value="Change Size" onclick="something()" />                   
    <br/>
    <script>
       document.write('<iframe id="frame1" name="frame1" width="200" height="197" src="http:// .... .xbap?id=' + 1 + '" frameborder="1" border="1" style="border: 1px solid #000000;" />');
    </script>
</body>
</html>

How should i configure my vb.net class and html file so that it works? thank you.

This question seems to be unanswered, and is most likely bit duplicate with other questions out there.

But any how, I have created a blog post where there is a javascript button that calls function from xbap. This solution works with latest browsers out there.
