Rerender on new route or transition

Maybe you can try the following code (not tested):

// My plugin initializer
export default {

	name: 'myPlugin',

	initialize(container) {

		// Reopen the router to add a didTransition hook
		const router = container.lookup('router:main')
		router.reopen({
			doSomething: function() {
				// Wait for rendering to be over. THIS DOESN'T WORK IN ALL CASES. 
				// In fact, there is no way to be sure rendering is complete, because 
				// a 'complete rendering' is meaningless (think about a looping DOM  
				// animation)
				Ember.run.schedule('afterRender', null, () => {
					// Do your stuff here
					...
				})
			}.on('didTransition')
		})

	}

}
