问题 I have created an AngularJS webapp that uses node, loopback, ui-router, and bootstrap. I am building my app using Brackets and when I launch their live preview (http://127.0.0.1:53490/index.html).

问题 I have tried an example from http://apidocs.strongloop.com/loopback/#model: MyModel.on('changed', function(inst) { console.log('model with id %s has been changed', inst.id); // => model with id 1 has been changed }); I replaced MyModel with actual model name.
