C# Invoke JavaScript in WebBrowser

I am trying to invoke JavaScript method in my WebBrowser :

WebBrowser webBrowser = new WebBrowser();
webBrowser.NavigateToString(html);
webBrowser.LoadCompleted += ((s, r) =>
{
         try
         {
                 object tmp = webBrowser.InvokeScript("GetData");
         }
         catch (Exception exc)
         {
         }
});

This is the HTML :

<html><head>
<meta http-equiv="content-type" content="text/html; charset=ISO-8859-1">
<title></title>

<script type="text/javascript">
    function GetData ()
    {
        return 50;
    }

</script>

But when i invoke the javascript with :

object tmp = webBrowser.InvokeScript("GetData");

I get Exception:

Message:

An unknown error has occurred. Error: 80020006.

You need to set the WebBrowser.IsScriptEnabled to true (it is false by default)
