I have the following code:

 $('#change').dialog({
            autoOpen: false,
            width: 380,
            buttons: {
                "Close": function() {
                    $(this).dialog("close");
                },
                "Accept": function() {
                    var test = $("#ChangePasswordForm").submit();
                    alert(test);
                }
            }
        });

In my controller I want to return a string

  [AcceptVerbs(HttpVerbs.Post)]
    public string ChangePassword(string Name)
    {
        var msg = "Cool!";

if (name != null) return msg; }

How can I do that?
