I tried
myList.data()[0] = 'test'
I was able to change the first element of the data array to "test". I
confirmed it by scrolling the list down and then scrolling back up the
first element to see the first element changed to "test".
I noticed there was a method redrawRow(rowNumber). I tried
myList.redrawRow(0), but it didn't work. I then tried
alert(myList.redrawRow) to see if the function was being called and it
gave me undefined. Has this method not been implemented yet?
