I'm posting this reply at the risk of ridicule because I'm admittedly pretty noob at this stuff (only been learning a month or two), but I was able to handle a similar situation (changing time zones) just doing this:

$(".timezonedropdown").change(function() {
    var newVal = $(this).val();
    if(!confirm("Are you sure?")) {
        $(this).val($(this).closest('select').attr("data-originaltimezone"));
    }
});

Then in my html I included data-originaltimezone="whatever" in the select. I had the class timezonedropdown for the select as well. Hope that helps! :)
