Cannot iterate over data array more than once in a single view

I'm having an issue iterating over an array of data more than one time in a single view.

It works when iterating over the data once, as you can see here: http://jsfiddle.net/6LABZ/5/

But as soon as I include another iteration, like on http://jsfiddle.net/F3k4v/1/, I get no output from the template/view.
