Discard model changes without Ember-Data

I have a model created from a JSON object that has many properties related to the user interface (settings panel). I would like to allow the user to update their settings, but I also need a way to revert their changes to the model after making changes to the user interface.

I see many examples using Ember-Data, but we do not use this; I also don't see any obvious patterns / methods in Ember docs. Is there a commonly used pattern to achieve rollback on models without Ember-Data?

I like to use the rollbackAttributes () method for the model.

import Ember from 'ember';

export default Ember.Component.extend({
actions: {        
    cancelEdit: function() {
        var model = this.get('objectBeingEdited');
        model.rollbackAttributes();
        this.toggleProperty('isEditing');
        }
    }
});
