Why doesn't scrolling the slider with the mouse work in the parallax slider?

Question

JavaScript

Slider demo
Here's my script, which is supposed to scroll the slides with the mouse wheel, but why doesn't it work. Where is the problem?
Perhaps the button names are not navNext, navPrev for this slider?

$(document).ready(function () {
        $('#da-slider').cslider();
        $('#da-slider').mousewheel(function(e) {
            e.preventDefault();

            if (e.deltaY < 0) {
              $(this).cslider('navNext');
            } else {
              $(this).cslider('navPrev');
            }
          });
      });
