In addition to showing the challenge's `name`. I also want to show its `deadline` next to the `name`.

It would look like this for example:

```
Visit London 09/09/16
Make $1,000,000 10/15/18
Knit a Scarf 01/11/19

```

Instead of just this:

```
<%= f.collection_select :challenge_id, current_user.challenges.order(:deadline),:id,:name, include_blank: true %>

```
