I am new to ember, just started this week. Latest version of ember is used. My use case is page has 2 sections. one list view & other details view. setup 2 templates, controllers for handling separate data. For details view using a component. Data is shown in static fashion correctly. Now based on a click on list view, want to show different data in details view. Based on click the list controller property is changed & was expecting that the component can watch it and make its own changes. Used observer on controller property from component but unable to proceed. Is there any way to do this?
