jQuery Button.click() event is triggered twice

Your current code works, you can try it here: http://jsfiddle.net/s4UyH/

You have something outside the example triggering another .click(), check for other handlers that are also triggering a click event on that element.

In that case, we can do the following

$('selected').unbind('click').bind('click', function (e) {
  do_something();
});

I had the event firing two times initially, when the page get refreshed it fires four times. It was after many fruitless hours before I figured out with a google search.

I must also say that the code initially was working until I started using the JQueryUI accordion widget.
