calling Javascript from c# using awesomium

Question

I'm trying awesomium for create a basic app, I'm testing the js <----> c# communication but this doesn't seem work well...I create a local html and open it..so far so good..but when I try call js nothing happen, no error, no bug, nothing, simply this doesn't call js..

my basic js code is:

 var base = {

    newItem : function(item){
    $("#botones").append('<div class="botonMenu">' + item + '</div>');
  },

  other : function(){
      alert("hi!!");
  }

  }

if I test this inside firebug obviously I can call my functions well and the items are created or the alert box...

now..my c# code is this

//I've wrote this code inside the winForms sample..but change the code for load
//my local file and call js....


WebCore.BaseDirectory = @"C:\Documents and Settings\ME\dummytests\codes\views";
webView.LoadFile("base.html");


JSValue param1 = new JSValue("nameItem");
webView.CallJavascriptFunction("base", "other");
webView.CallJavascriptFunction("base","newItem", param1);
webView.Focus();

the file is load well but the js communication didn't work thanks so much and I hope can help me...this awesomium really look awesome

The problem is that you're trying to call the Javascript on the page before it has finished loading. If you wait until after load has completed, you should see it execute correctly.

webView.LoadCompleted += ExecuteJavascript;

WebCore.BaseDirectory = @"C:\Documents and Settings\ME\dummytests\codes\views";
webView.LoadFile("base.html");

...

private void ExecuteJavascript(object sender, EventArgs eventArgs)
{
    JSValue param1 = new JSValue("nameItem");
    webView.CallJavascriptFunction("base", "other");
    webView.CallJavascriptFunction("base", "newItem", param1);
    webView.Focus();
}
