Shoutbox

In this specific case, I'd use `e.currentTarget` and then proper coffeescript `this` rules. http://stackoverflow.com/questions/12648187/coffeescript-how-to-use-both-fat-arrow-and-this

```coffeescript
@element.find('.shout-input').keypress (e) =>
  text = $.trim($(e.target).val())
  if (e.keyCode == 13 && text.length)
    @create text, (data) => @update()
    $(e.target).val('')
```
