jQuery .on function for future elements, as .live is deprecated

I need to add a handler for the click event of future <div> elements, that don't exist yet. Normally, I would use jQuery's .live function to handle this, but it seems that it is now deprecated in favor of .on.

To use the .on method in this manner, jQuery suggests setting the selector parameter, to allow creating a delegated event, and offers this example code:

$("#dataTable tbody").on("click", "tr", function(event){
    alert($(this).text());
});

That's all fine and good, but what do I put in for my intial selector, where they have #dataTable tbody? Note that $.on() doesn't work.
