.scroll() not working jquery

I am using jQuery to check if a div is scrolled. It works on window, But it is not working on specific div.

Works fine:

 $(window).scroll(function() {
    console.log('scroll happened');
 });

Not Wokring Fine:

$('.ui-multiselect-checkboxes').scroll(function(){ 
    console.log('scroll happened');
});

HTML I am using ERIC Hynds Multiselect. So scroll is present on its ul with class ui-multiselect-checkboxes. You can see live example here

Try something like this

$(document).ready(function(){

    $('.ui-multiselect-checkboxes').bind('scroll',chk_scroll);
});


function chk_scroll(e)
{
    var elem = $(e.currentTarget);
    if (elem[0].scrollHeight - elem.scrollTop() == elem.outerHeight()) 
    {
        console.log("Scrolled");
    }

}

create delegate event because these are created dynamically by youe multiselect plugin.

$(document).on('scroll', '.ui-multiselect-checkboxes', function(){ 
    console.log('scroll happened');
});

Try:

$(document).on('scroll', '.ui-multiselect-checkboxes', function(){ 
    console.log('scroll happened');
});

This is because these elements are dynamically created by multiselect plugin.
