Can't update template from controller

Hm…how are you invoking this someFun function?

By default .send does not creates a runloop. This means if you are invoking the function directly from console, the change would not get flushed to the template. Try wrapping the content of someFun in a runloop.

...
someFun: function() {
  Ember.run.join(this, function() {
    this.get('controllers.another').send('reload');
  });
}
