Change Event for a Textbox using JQuery

If you want to create 'Change Event' for a textbox using JQuery then I like the below process like a VB6.0. It works great. There are several way you can do that like blur event, keyup, paste, mouseup etc. But this is the best for me. You can try it in your project if the below process works great then just give a good comments.

$("#idTextBox").bind('input propertychange', function() {
        //Your code goes here.

        var qty = $('#txtQty').val();
          var rate = $('#txtRate').val();
          var amt = qty * rate;
       
           $('#txtAmt').val(amt.toFixed(2));

                   alert('Change detected');

 });
