Trigger a function when a jQuery UI tab is clicked/made active?

Question

I'm using jQuery tabs and the content in one of the tabs is retrieved via an AJAX call. But I don't want to trigger the call until the tab is clicked (made active) because the user might not necessarily click it. What's the best way to do this?

jQuery UI provides select and show events for the tabs, but these fire when any tab is selected or shown, not just a specific one (as far as I know).

I've also tried assigning a click event to the specific tab's ID:

$("#my-tab").click(function(){
...
     $.post(URL, function(data){
          ...
     });
...
}

But this seemingly has no effect and the call is never triggered.

The ticked solution doesn't work any more because jquery-ui has changed. Also you need to call the tabs function on the entire tab-set, not just one tab. And ui.index needs to be replaced. If the 2nd panel has the id "tab2" then you can use:

$("#tabs").tabs({
    activate: function(event, ui) {
       if (ui.newPanel.selector == "#tab2") {
            alert("tab 2 selected");
       }
    }
});
