MoinMoin: DuffDave/AjaxForm

The Idea is to make simple dummy form as a macro with the use of ajax. Here my first try. The Request was sent but I ll get back the whole page. Where is the mistake?

def execute(macro, request):
    template = '''
    <script type="text/javascript">
        $(document).ready(function() {
            $("#login_form").submit(function() {
                var unameval = $("#username").val();
                var pwordval = $("#password").val();
                $.post("intern", { username: unameval,
                password: pwordval }, function(data) {
                    $("#status p").html(data);
                });
                return false;
            });
        });
    </script>
    <form id="login_form" method="post">
        <p>Username: <input type="text" id="username" /></p>
        <p>Password: <input type="password" id="password" /></p>
        <p><input type="submit" value="Login" name="create"/></p>
    </form>
    <div id="status">
        <p></p>
    </div>
    '''
    
    request = macro.request
    form = request.form

    submitted = form.has_key('create')
    
    if submitted: # user pressed button
        return validate()
    else:
        return template
    
def validate(): 
    form = request.form
    
    username = form['username']
    password = form['password']
    if (username == "test" and password == "password"):
        return "<strong>Login succeeded!</strong>"
    else:
        return "<strong>Login failed! Please try again.</strong>"
