How to decouple Backbone Router and Controller in RequireJS modules?

Question

JavaScript

SPA refactoring, a cyclic dependency has arisen.
There is a Controller module, where all the logic and actions in the application, incl. display view "pages". And there is a separate Backbone Router module responsible for navigation.
When the application is initialized, depending on the received initial data, the Controller directs to one or another "page" displays the corresponding. view and includes resp. URL in Router.
When navigating menus in an application, Router jumps to some “pages” by calling the Controller.go(page) method or performs other actions from the Controller, such as refreshing data from the server.
How to properly decouple these two modules so that maybe only one depends on the other? Throw in the opposite direction Event'y?
