Combining Ergec's answer and Pere's comment:

function watchScrollPosition(callback, distance, interval) {
    var $window = $(window),
        $document = $(document);

    var checkScrollPosition = function() {
        var top = $document.height() - $window.height() - distance;

        if ($window.scrollTop() >= top) {
            callback();
        }
    };

    setInterval(checkScrollPosition, interval);
}

distance is the number of pixels from the bottom of the screen when the callback will fire.

interval is how often the check will run (in milliseconds; 250-1000 is reasonable).
