You can use the addArrayObserver method to find items added/removed from an array.

The code will look something like this

that.get('content').addArrayObserver(this, {
  willChange: Ember.K,
  didChange: function(array, start, removeCount, addCount) {
    alert(array[start]);
  }
});

More information can be found here.

Here is a link to a working demo.
