Messi jQuery Confirmation Box Redirect

I have a jQuery script in WebForms that I'm trying to get to display a message on a button click event. I have the script in my .aspx file and I'm calling it in code-behind. The issue is how do I redirect if a user clicks the confirm and not the cancel button?

.ASPX Script:

<script type="text/javascript">

        $(window).unload(function () {
            CloseWindow();
        })
        //var newEmployeeDetail = document.getElementById(hfNe)

        function confirmAppointEmployee() {
            debugger;
            Messi.ask("Employee appointed successfully",
                function (val) {
                    if (val == false) {
                    $("[id*=Cancel]").click();
                }
                else {
                        $("[id*=Confirm]").click();
                }

            }, {
                buttons: [{ id: '0', label: 'Confirm', val: true, 'class': 'btn-primary' }, { id: '0', label: 'Cancel', val: false }]
            });
        }

    </script>

Code Behind:

 ClientScript.RegisterStartupScript(this.GetType(), "Success", "<script>confirmQuickAppointEmployee()</script>"); 

The below code is the string that needs to be called to redirect the user.

private string PersonalInformationDetailUrl = Company.Framework.SmartNavigationPersonnel.SmartNavigation.GetUrlByPageName(Company.Framework.SmartNavigationPersonnel.SmartNavigation.PageNameList.PersonalInformationDetail) + "?AllowAddOption=true&AllowDeleteOption=true&RefreshMenuPage=true";

I have tried the below method but both the cancel and confirm button do the same thing.

  var confirm = "$(document).ready(function(){ new Messi('Employee appointed successfully', " +
                        "{title: 'Title', buttons: [{id: 0, label: 'Close', val: 'false'},{id: 0, label: 'Confirm', val: 'true'}], " +
                        "callback: function(val) { window.location.href = '" + Functions.FixClientUrl(PersonalInformationDetailUrl) + "' }}); });";
                    this.Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "confirm", confirm, true);
