When you navigate to a page and provide a bindingContext, it would be nice this context to become the bindingContext of the page. In this way, you would not have to subscribe to each page's navigatedTo event simply to set its bindingContext. Instead you can do it like this:

    frameModule.topmost().navigate({
        moduleName: "details-page",
        bindingContext: new DetailsViewModel(id),
        animated: true,
        transition: {name: "slide"}
    });
