javascript - detect key press on modal dialog not working

Question

I would like to detect whether the user has pressed any key when a modal is shown. I tried the following code but the events are not fired.

Code snippet:

   $("#modal_confirmation_dp_change").on('keydown keyup input', function ( e ) {
         alert();
        });

If I try to test click event, it is fired.

   $("#modal_confirmation_dp_change").on('click', function ( e ) {
            alert();
        });

I am using twitter bootstrap modal. Am I missing something?

ANSWER: I found the solution to my problem. It seems like I should not point to the id of the modal so that the keypress event will be detected.

I found the solution to my problem. It seems like I should not point to the id of the modal so that the keypress event will be detected.

$(document).on('keydown keyup input click',  function (e) {
if($('#modal_confirmation_dp_change').is(':visible')) {
            var key = e.which;
                if (key == 13) { //This is an ENTER 
                    $('#changed_dp_ok').click();
                }
        }
    });
