There are no recent events for upand down. You can use eventchange

$(".counter").change(function () {
   alert($(this).val());      
})

Demo

You can try something like: you can save the previous value and compare with the current value and identify up or down

$(".counter").change(function () {
    if ($(this).data('old-value') < $(this).val()) {
        alert('Alert up');
    } else {
        alert('Alert dowm');
    }
    $(this).data('old-value', $(this).val());
})

You must do this:

var $counter = $("your_counter");
var number = $counter.val();

$counter.change(function () {
   if($counter.val() > number)
       alert('up');
   else
       alert('down');
   number = $counter.val();
});
