JQuery :: Listen For Change In An Element's Children

I have a UL that loads in dynamically after the DOM has already finished loading via and external API that doesn't have a callback function for when it's finished. However, I need to manipulate the children of the UL once it's loaded in, so I need some type of listener for when the UL changes.I need an event to fire when an element or it's children change.Is there anything like this in jQuery? Otherwise I'm going to have to create a setInterval to polloccasionallyto see if the UL has loaded, and that sounds sloppy.
