jQuery event handler .on() not working

Maybe you should do:

jQuery("body").on("click",".date_picker_disabled", function(event){
          alert('hi');
  });

in this way you attach the event handler to the bosy and specify to fire that event only when that selector ".date_picker_disabled" is matched.
BTW this is exactly how live() worked
