Asynchronous call disregarded by Awesomium
===

in Awesomium-sharp, I wrote my C# code like this:
    
    WebControl webControl = new WebControl();
    webControl.CreateObject("external");
    SetObjectCallback("external", "JSCallback", OnJSCallback);

    public void OnJSCallback(object sender, JSCallbackEventArgs e)
    {
       //handle calls from Javascript
    }

and the javascript code is like this:
    
    external.JSCallback("hello ", "world");
    external.JSCallback("wtf ", "dude");

The strange problem is that the second call from Javascript seems to be diregarded and 
never executed. 
What's wrong with my code? and btw, the version of AwesomiumSharp is V1.6.6
