How to update Parent Component data from Child Component without two way data binding in angular 1.5.x?

问题

Sorry if it's a silly question but i am a noob in angular 1.5.x

I am using es6 class based components with one way data bindings throughout the app(best practices as far as i know).

I have a Container Component. It has a Sidebar Component and a Content Component.

I fetch the menu options (array or object) in Container Component and pass it to Sidebar Component and Content Component using one way data binding as attributes.

I want to update the Container Component whenever i change menu options in Sidebar Component or Content Component and it should be reflected in both the child components.

I don't seem to find a way ( without two way data binding ) to do it in angular 1.5 without using $scope events or Service.
