Ember add customEvents

I'm using Ember 2.9 and would like to use the "paste" event.

How I can add paste as an customEvent on start up the application:

This is my current app.js:

import Ember from 'ember';
import Resolver from './resolver';
import loadInitializers from 'ember-load-initializers';
import config from './config/environment';

let App;

Ember.MODEL_FACTORY_INJECTIONS = true;

App = Ember.Application.extend({
  modulePrefix: config.modulePrefix,
  podModulePrefix: config.podModulePrefix,
  Resolver
});

loadInitializers(App, config.modulePrefix);

export default App;
