Rails 3.1. Cocoon link_to_add_association example needed

pls show any example of using Cocoon's 'link_to_add_association' with html_options. https://github.com/nathanvda/cocoon

Documentation says:

html_options: extra html-options (see link_to) There are two extra options that allow to conrol the placement of the new link-data:

    data-association-insertion-node : the jquery selector of the node
    data-association-insertion-position : insert the new data before or after the given node.

But i can not understand what to do, if i want insert partial just before my "add element" link. Not just after parent's div begin. This not gonna work:

<%= link_to_add_association "add element", f, :production_years, :position => "after_all" %>

If you want to do it using data-attributes you can do:

<%= link_to_add_association 'Add Item', f, :items, :data => {"association-insertion-method" => "before" } %>

I will admit that is a bit obscure, and maybe I should provide an example in the code.

In your application.js you should write something like:

$(document).ready(function() {
    $("a.add_fields").
      data("association-insertion-position", 'before').
      data("association-insertion-node", 'this');
});

where a.add_fields will select your clickable link. I have only recently updated the readme with a better explanation how the insertion can be handled.

Hope this helps.
