jQuery window scroll event does not fire up

I'm trying to implement a simple "stay inside the viewport" behaviour to a div via jquery. For that i need to bind a function to the scroll event of the window, but i can't seem to get it to fire up: nothing happens. I've tried a simple alert(), console.log() no dice. An idea what i'm doing wrong?

This code :

$(window).scroll(function () {

sits in script.js, located at the very bottom of my html file

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script src="js/script.js"></script>

OK, worked it out.

Your CSS is actually setting the rest of the document to not show overflow therefore the document itself isn't scrolling. the easiest fix for this is bind the event to the thing that is scrolling which in your case is div#page.

So its easy as changing:

$(document).scroll(function() {  // OR  $(window).scroll(function() {
    didScroll = true;


$('div#page').scroll(function() {
    didScroll = true;
