My Coffee Script test. I am trying to figure out what is wrong with my scoping to make it not increment.

test.coffee

jQuery ->
  count = 0 
  $("a").click (e) ->
    e.preventDefault()
    alert("Hello World #{++count}")

test.js

jQuery(function() {
  var count;
  count = 0;
  return $("a").click(function(e) {
    e.preventDefault();
    return alert("Hello World " + (++count));
  });
});
