React.js: Sortable component

Question

I used a SmartSortable snippet by Pete Hunt from React.js Google Group that intergates jQuery UI sortable with React.

Unfortunately, after using it, editing input fields makes the text cursor to just to the end of the currently edited input field.

Removing <SmartSortable> from the example fixes the problem.

Why is it happening? I believe, the <input>’s value get’s updated despite being exactly the same; I don’t understand why.
