Capture scroll event on div

Question

I\'m trying to capture the scroll event within a Backbone.Marionette.CompositeView, but without success.

As an exercise, I\'m rewriting http://www.atinux.fr/backbone

I don't know what your el is, but I suspect it's something that does not receive the scroll event. Since Backbone delegates event handling to jQuery, have a look at what jQuery says about the scroll event:

The scroll event is sent to an element when the user scrolls to a different place in the element. It applies to window objects, but also to scrollable frames and elements with the overflow CSS property set to scroll (or auto when the element's explicit height or width is less than the height or width of its contents).

Unless your el satisfies those conditions, it will not receive the scroll event. You will have to put the event handler on window or some other element that does receive it.
