You can use this :

$( ".selector" ).dialog({
  open: function( event, ui ) {}
});

or the event listener .on

$( ".selector" ).on( "dialogopen", function( event, ui ) {} );

        alert('hello');

It will display alert after clicking on the OK button.

$( "#WaitingDialog").html("Message you want to display").dialog({
   modal: true,
   buttons: { 
    Ok: function() {
       alert("hello");
    }
}});

It will display alert after opening the modal

$( "#WaitingDialog").html("Message you want to display").dialog({
    modal: true,
    buttons: { 
        open: function( event, ui ) {
              alert('hello');
          }
    }});
