index not updated properly

[ghedamat]

Hi!

I'm in the process of updating what @cibernox did here https://github.com/cibernox/ember-power-select-collection

In its newest version ember-power-select relies on the index yielded property of the #each helper.

It appears that this is not playing super well with ember-collection and when power-select filters the list the indexes are not updated properly.

ember-collection exposes an index but maybe I'm simply misunderstanding its functionality?

I'll try to create a reproduction repository as soon as I can, in the meantime here's a video from this happening in my company's app

I'm rendering only the indexes in the list instead of the full content and you can see they're not contiguous

thanks!

also to be noted, I have a workaround for ember-power-select that doesn't rely on the index property but I still wonder if index is correct

Sorry, just haven't had time to figure out why those tests are failing, but basically when reusing cells we aren't updating the index that gets exposed.

@raytiley no problem, I missed that #110 was the same.

As mentioned I have a workaround for now anyway.

Thanks for the quick response!
