The only solution I’ve found so far is to switch to Component and use bufferedRender and to observe for changes in local variable, then call re-render.

```
export default Ember.Component.extend(bufferedRender({

  @on("init")
  _updateContent() {
    if (!this.get('content')) {
      ajax("/growfaq.json").then(data => {
        this.set('content', data);
      });
    }
  }

  @observes('content')
  _rerenderOnChange() {
    this.rerenderBuffer();
  },

  
}));

```
