Hmm, can you clarify what you mean by "the removed one will be changed"?

I don't really follow the problem you encounter and I don't see how using the new_ prefix solves anything. More over, the prefix addition broke the code :)

I'll try to explain what this code does:

• The number of elements is counted when the page is loaded, this count is set as the index data element on the collection holder. This happends on the line you choosed. (assume this is 3)
• Whenever an input is added, this index data element is increased with one
• Whenever you remove an input, the input is removed and the index data element remains unchanged.

See this JSfiddle for an example of the code: http://jsfiddle.net/847Kf/2/

@wouterj IIRC, js fiddle keeps forever a fiddle. Do you think it's a good idea to add you good fiddle to the doc?

Hmm, I think that's a cool idea, with really now cost, since it would just be a small link.

s/now/no ? I'm not he only one to do that kind of mistake ;)

Hmm, JSfiddle promised to keep all JSfiddle until Beta, they didn't promise the rules after it (some say they keep hosting the snippets). Since JSfiddle is now in alpha, it might be a bit tricky...

But yeah, if I can make the example a little bit prettier, it'll be great to have in the docs indeed!

did not know that. But jsfiffle exists since 2009. They will stay in alpha for ever ;)

@lyrixx ironically, I think I make more typos than most people :).

So what's the status then? Seems like this is not a real issue and we should close it. But then Wouter should also create a new PR when he has time linking to the jsfiddle?

I'm closing this - Wouter added a JSFiddle where you can play and modify the code.
