javascript - dispatchEvent not triggering jQuery.on() event listener -

-

I have the following code that triggers custom name events: 

  elem.addEventListener ('Click', function (event) {event.preventDefault (); // some processing content var event = new event ('custom_event'); this.dispatchEvent (event);});

If I try to capture custom events with jQuery.on (), then it works, but only when I'm not using the Dynate Selector filter.

Then it works: 

  $ ('selector'). ('Custom_event', function () {// works});

but not so: 

  $ (document) .on ('custom_event', 'selector', function () {// does not work}); Can anyone put light on it? Here is the problem showing.   
 
 
 is not the event bubble by default, so when you create an event, The form needs to be passed in the form of  bubbles: true  that you want to bunk the incident. You can use to do this. 
 
 If you are using Event Delegation to register event handlers, use Event Bubbleing to work. 
 
 
 
 
  document.querySelectorAll ('.button') [0] .addEventListener ('click', function (e) {var event = new custom event ('custom_evolution', {bubbles: true} ); This.dispatchEvent (event);}); $ (Document) .on ('custom_event', '.button', function () {warning ('custom event has been captured [selector filter]');}); $ ('.button'). ('Custom_event', function) {Warning ('Custom Event Captured');});  
 
  & lt; Script src = "https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js" & gt; & Lt; / Script & gt; & Lt; Button class = "button" & gt; Click me & lt; / Button & gt;

So I have to know whether the property has been allocated or set to zero. I'm aware of INotifyPropertyChanged , but in my case I'm not sure that since this change I have changed my car properties car do not want to monitor the property. Any idea how to accomplish this? In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
