Column sorting doesn't occur on first click after initial render of the grid

Click on the second column header (not the first as this fiddle also demonstrates issue #7).

Notice that the first click does nothing, but on the second and subsequent clicks, the grid sorts as expected.

It looks like it's sorting correctly since the initial sort for column 2 is already in ascending order. If I reverse that it works as expected: http://jsfiddle.net/vYZQu/4/

On grids with lots of data, this would be more of an edge case, but on smaller grids this would occur more frequently. Would it be possible to detect if the order was already sorted and do the opposite?
