  4. Brian García 2016-05-10 Thanks, as you can see the last log should be 'changed secondTestFieldexpected secondTestField' as the above ones but instead it is 'changed firstTestFieldexpected secondTestField' when the change event is binded only to secondTestField. Regards,
  5. Feon Sua Xin Miao 2017-03-09 Please add to config.json "backbone": "1.1.2" and use [model.changedAttributes](http://backbonejs.org/#Model-changedAttributes) in the change event callback to retrieve a hash of only the model's attributes that have changed.
