jquery datepicker on esc key event

I'm trying to put a date value in the input box for the date picker when the user click on the key ESC (e.keyCode == 27) once he as open the datepicker.

My test case:

1) Click on the input box, the date picker show up;

2) The user decide to cancel the selection by clicking on the esc key.

3) The following date should be then put as default (01/01/2011) in the input box since he has not selected any da开发者_JAVA技巧te.

Please fork my Fiddle

$("#input").keyup(function(e) {
    if (e.keyCode == 27) {
        $("#input").val("01/01/2011");
    }
});
