loadTraits doesn't exists after upgrade from legacy api.

After upgrade to new API like below, I got error loadTraits doesn't exist. I wonder with the new API how does it inherit defaultModel?

Components.addType('component-id', {
model: defaultModel.extend({

to

Components.addType('component-id', {
model: {

Show the complete code please

I found example suggest to use this.getTrait().attributes, but it seems I should just use this.attributes
