javascript - jQuery Custom Event not triggering in AJAX Success Callback -


i experimenting jquery custom events in application.

in jquery ajax request code below, in success callback trying trigger() custom event

it not seem triggering though. not able done in success callback , needs called elsewhere?

jquery ajax request code 

// request task record using ajax request server var jqxhr = $.ajax({     type: 'post',     async: false,     contenttype: 'application/json; charset=utf-8',     datatype: 'json',     url: projecttaskmodal.cache.gettaskrecordurlendpoint,     data: {         action: 'load-task-record',         task_id: taskid     },     success: function(data) {          // non relevant code removed demo          // event not being triggered....         // publish 'task-modal-data-loaded' event subscribers         $.event.trigger({             type: 'task-modal-data-loaded',             source: 'ajax',             message: 'task modal object loaded ajax request',             time: new date()         });      } }); // end ajax request

custom event subscriber

$(document).on('task-modal-data-loaded', function(event) {     //alert('task modal object loaded');     console.log('custom app events: event: task-modal-data-loaded source: '+event.source+' message: '+event.message+' time: '+event.time); });

from discussion, problem when event triggered handler not yet added dom.

so making sure event handler added before event fired solve probelm
