when i want to detect the bottom of my page i use this code which worked fine in a test-file (link below):

```
$(window).scroll(function() {
    $(window).scrollTop() + $(window).height() == $(document).height(){
       alert(at bottom);
    }
}

```

But in my final file the exact same code only detects scrolling to the top. can anyone see the mistake or provide a better solution?
