Tech gotcha of the day: kogrid needs knockoutjs version 2.2 and above

If you have been using knockoutjs for a while and then you heard of a beautiful grid that will work well with knockoutjs, aka kogrid, forewarned: To use kogrid successfully, you have to update knockoutjs to version 2.2 and above, otherwise you will get an empty webpage with no grid and when you F12, you will see a JavaScript funtion error of something like the object doesn't have a method "seek".
