Ember-data custom didCreateRecord event

didCreateRecord.js

/* 
 * The `didCreate` event on a DS.Model does not behave like one would expect.
 * It actually only ever fires when you createRecord AND then save the record.
 *
 * This custom eventing below is how you achieve a the expected event.
 * This is useful in the case where you have relational objects that you want 
 * to auto-create when a record is created.  Or, some custom logic to implement 
 * once the record is created.  Likely very useful where you want to setup 
 * observers for things like validation.  Placing them in `init` wouldn't
 * be ideal since they will trigger the first time the model is initialized
 * and sets its initial values.
 *
 * Demo: http://emberjs.jsbin.com/juyejacaje/1/edit?html,js,console,output
