Durandal rebind when navigating to same module and view with different data

I have a pair viewmodel/view in my application that it is used for displaying different data. The data that is displayed is generated by some user input and a separate route for each set of data is registered on the router.

The problem is that because the same view/viewmodel is used for different routes, when navigating between them, the binding between view-viewmodel is not refreshed.

Hooking up to canReuseForRoute callback I managed to get the viewModel refresh, but the view is not refreshed.

I tried to use cacheVews on the router binding but the views were still not refreshed.

How can I make the router/routing composition refresh when navigating to a different route that is using the same view/viewmodel?

EDIT : (more info) Hooking on the binding callback I discovered that Durandal binds the view only the first time the module is used. If I try to navigate to a different route with the same module (view/viewmodel) it does not call the binding callback again.

Try overriding areSameItem on the activator as explained in this answer. Returning false should get Durandal to go through the whole page lifecycle again, whereas I think using canReuseForRoute doesn't necessarily.
