You can use .toggle(), like this:

$("#myButton").toggle(function() {
  //click first time 
}, function () {
  //click second time
});

You can add as many as you want actually, it just cycles through them, If you need to bomb out after the second click, just .unbind() by adding a $(this).unbind('click') at the bottom of the last click function, like this:

$("#myButton").toggle(function() {
  //click first time 
}, function () {
  //click second time
  $(this).unbind('click'); //without this, it goes back to the first function
                           //on the next click
});
