I am iterating a list of `entries` and would like to display the content of each entry within the list, but only when on the respective entry's route.

i.e. - When on route `/entries/2`

```
* link to entry 1
* link to entry 2

  content for entry 2

* link to entry 3

```

Unfortunately, it seems I can't use `{{outlet}}` within the `{{#each entry}}` loop.

Initially I tried to set `isActive` to true within `setupController` on the route, and check for that within the template, but it does not seem like there is a good way to remove that flag when you navigate to `/entries/3` (`deactivate` only works when moving away from `/entries/:entry_id` entirely) . See [Is there an opposite of setupController?](https://stackoverflow.com/questions/16493203/is-there-an-opposite-of-setupcontroller?noredirect=1#comment23691823_16493203) for more on this.

What is the best way to do this with Ember?
