title: Embjers store.createRecord or store.push not updating view
body: <p>I'm trying to create a new record and push it into the store. I can persist it  just fine (and i'll push to the store after successfully persisting, once i figure this out), but the view/template isn't being refreshed. I know persistence works because, if I refresh the entire page, the new record appears.</p>
  
  <p>I also tried this.store.push(), and nothing happens. I've looked around and everyone seems to be using filter() but only on a child set of records in a parent controller...</p>
  
  <p>Thanks in advance, i have feeling its something really basic. </p>
