The problem is in how you're applying the decrement operator. If you
put it at the end of the number, as in:
number--
Then, the current number will be returned, THEN decremented. That's
what's happening here.
Simply put the operator before the number, so it is decremented THEN
returned.
$('.number').html( --count );
