I was having trouble with the onkeydown event and had success with onkeyup. Here's the code I came up with to count down the remaining characters (with a limit of 120)

$(function() {
  var input = $('#my-input'), display = $('.char-count'), count = 0, limit = 120;

  count = input.val().length
  remaining = limit - count
  update(remaining);

  input.keyup(function(e) {
    count = $(this).val().length;
    remaining = limit - count;

    update(remaining);
  });

  function update(count) {
    var txt = ( Math.abs(count) === 1 ) ? count + ' Character Remaining' :  count + ' Characters Remaining'
    display.html(txt);
  }

});
