$("#form_id").live("ajax:beforeSend", function(e, xhr, settings) {
  

});
$("#new_manual_air_booking").live("ajax:success", function(e, data, status, xhr) {
   alert("Added");
   render_time_slot(DI.day_wrapper_id,DI.day_date,DI.trip_id);
   $("#daily_itinerary_event_model").html('');

}).live("ajax:error", function(e, xhr, status, error) {
    alert("Error");
});

 live => on

Instead of live you can use on because live deprecated few year back, syntax for using on is:

$(document).on('ajax:beforeSend','#form_id',function(e, xhr, settings) {
  

}); 

 Instead of document you can wright parent element id of element which we are going to target.
