Datepicker - Custom text below calendar not working

Datepicker - Custom text below calendar not working

I am having trouble with displaying a custom text below the calendar.

The datepicker consists of highlighting dates captured from database, and I want a custom text to sisplay below the calendar as shown here: http://jsfiddle.net/william/ctqUa/1/

This is the code that is not working for me:
  1. $("#datepicker").datepicker().bind('click keyup', function() {
        if ($('#ui-datepicker-div :last-child').is('table'))
            $('#ui-datepicker-div').append('<p>hello world</p>');
    });


My complete code in jsfiddle: http://jsfiddle.net/kL4ur/

What is wrong?
