I am using built-in function UmbracoLoginController. It worked fine with login and logout. But I want to do further as If my ajax calls return 404 or 500, I would like to logout user automatically by showing a message "Your session has been timeout. ..."

using (Html.BeginUmbracoForm<UmbLoginStatusController>("HandleLogout"))
    {
         <fieldset>
             <legend></legend>
             <button class="k-button">Logout</button>
         </fieldset>

        @Html.HiddenFor(m => logoutModel.RedirectUrl)
    }

The code above work fine if user click Logout button. But how to make a request to logout user in this case without clicking on button. Thanks
