Issue using 1.10 table rows()

I've encountered an issue when attempting to follow the example for multi-row selections:

https://next.datatables.net/examples/api/select_row.html

The issue is, when I try to recreate the example and click the button nothing happens. The console shows the following error:

Uncaught TypeError: Object [object Object] has no method 'rows'

I've checked and made sure I'm not loading multiple instances of jQuery or datatables JS files. See the jsfiddle at:

Is this possibly a bug, or have I botched something here? I've tried using jQuery 1.10.2, 1.11.0, but encountered the same issue.
