Sails API (Ember frontend) rejecting changes

I'm getting started with Ember (CLI) and am trying to create a simple CRUD setup, using Sails as my API. Ember's loading all the data as expected, but won't save any changes. I've made some actions buttons to toggle Booleans, and increment a counter, but these just revert back. However, Sails' default attribute "updatedAt" is updated with the date of the attempted update.

It seems GET and DELETE work fine, but am I perhaps missing a step for PUT and POST to work properly?

I'm using the mphasize's sails-ember-blueprints, but haven't read about much trouble with them. here
