Query1.10 removes the.live() method and adds a.on() method to bind events to elements.

On (the events, the selector, [data], fn)

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

The above method binds events to all of this tr, but cannot bind events to new elements.

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

The above method binds an event to the tbody, where the tr can trigger the click event if the tr is a new element.
