The WebBrowser dose not fire java scripts

Question

See more:

The WebBrowser dose not fire any java scripts; Here it is one of them:

C#

public void WebBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    this.Document.InvokeScript("postform_open");
}

Even when I click on the link below in the WebBrowser:

HTML

<a onclick="postform_open();">Send</a><%--This html code cames from My Browser inspector--%>

What should I do to fix it? What I am missing?

For understanding that can I invoke an script or not I created a new project with only to Control. A button and a webBrowser; All of the code are just these:

C#

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();

            wb.ScriptErrorsSuppressed = true;

            wb.DocumentText = @"<html><head>
                <script type='text/javascript'>
                    function doIt() {
                        alert('hello again');
                        return 'i did it!';
                    }
                </script>
                </head><body>hello!</body></html>";
        }

        private void button1_Click(object sender, EventArgs e)
        {
            object x = this.wb.Document.InvokeScript("doIt");
        }
    }

the variable x will be null and no alert will appear. I am really confused.

I think you are miss understanding. The web site is not mine! and of course its my fault to not explaining well.
My Project is Windows Application.
I am trying to invoke a javascript in a website using WebBrowser.
