Good day.
I know that there is @this @this source, that can be used to observe itemController properties.
How can I use @this or something similar to observe itemController properties in such case:
Template:
{{#each headers itemController='headerItem'}}
{{! skip}}
{{/each}}
ArrayController:
headersPropertyChanged: function() {
}.observes('headers.@this.property'), // what should I use?
ArrayController has another itemController for main model.
Thanks.
