There can only be one instance of an ID on any given page. And nothing you did in this example will render the id #commentable. If you look at my example, I did not use an ID on each element. The selector in $('#commentable').each should be $('#parent_of_the_list div'), and you'll have to apply whatever ID you want to search for to a parent element of the commentables. If you want to do this in a slightly simpler manner, you could apply a classname to the commentables, using the div_for helper: <%= div_for(commentable, class: 'commentable') do %>. Then you can change the jQuery to $('.commentable') and that will also work.

Since I'm returning the new comment form shouldn't it be rendered in a div that looks something like post_14_comment_5 or something
