Strange binding

[Vladimir]

Hello,

i'd like using data-binding attribute into a template but the data object that's bound to an html tag is not correctly associated.

for exemple:
Simple binding: http://jsfiddle.net/rKQDM/7/
More complex (expressions & events): http://jsfiddle.net/rKQDM/5/

What's wrong?

Thanks in advance.

So, when you add a div the index of the collection change, you'll see it :
Working: http://jsfiddle.net/rKQDM/9/
Not working with adding a div tag: http://jsfiddle.net/rKQDM/8/

It's normal ?
