Hi Michelle!

Thanks for the feedback. Please see my comments inline below.

I already thought about that - will implement it this way - will be much

Well, I have done something really stupid here. Of course the binding should
not be performed in the onSelect listener but when the item is added to the
markup. Another thing that will simplify the code.

I also had difficulties with making up the name. 'itemTemplate' is probably
good, but will try to think of something better.

Oh, it seems these have come after introducing the serverOn option. It would
be pretty simple to move them after the block.

Seems like another pair of eyes are very useful for spotting obvious
problems. These all are sensible and I will work on eliminating them. It
will be great to have more notes like this.
