            data: { '__RequestVerificationToken': sToken, 'id': parseInt($(this).attr("title")) }
        })
        .done(function (data) {
            //Process MVC Data here
        })
        .fail(function (jqXHR, textStatus, errorThrown) {
            //Process Failure here
        });
    });
