JQGrid: How to confirm data "change" event?

I have a JQGrid with a select column. I'd like to require the user to "confirm" the change before it's committed to the database.

I can intercept the cell change and prevent the data from being submitted to the server, but by the time the event fires, the UI is already changed.

Is there a way to either catch a "before changed" event, or to revert the select element's value to whatever it was before the user changed it?

Here is how I'm currently catching the changed event

{
    name: 'ApplicationStatus', index: 'ApplicationStatus', width: 110, align: "left", sortable: true, editable: true, edittype: "select",
    editoptions: {
        value: StatusList,
        defaultValue: this.value,
        dataEvents: [
        {
            type: 'change',
            fn: function (e)
            {
                if (!confirm("Are you sure wish to change the Status?")){
                // HOW DO REVERT VALUE OF SELECT BOX HERE?
                    return;
                }
                $('.jqu-garid').block({ message: null });
                $.post("ApplicationStatusChangeto/", { NewStatus: this.value, ApplicationId: lastSelection }, function (data)
                {
                    if (data.success)
                    {
                        $('.jqu-garid').unblock();
                        $("#list47").trigger("reloadGrid");
                    }
                    else
                    {

                    }
                });
            }
        }]
    }, searchoptions: { sopt: ['cn'] }
}
