collection_check_boxes not working with class:"paper-check"

[s-mooches]

Howdy, I was playing around with PaperCSS on rails and ran into an issue with the collection_check_boxes not rendering the check box when the class "paper-check" is applied to a label builder.

    <%= form.collection_check_boxes :category_ids, Category.all, :id, :name do |b| %>
        <div class="col-4">
          <%= b.label  class:"paper-check" do %>
            <%= b.check_box data: { checkbox_select_all_target: "checkbox" } %>
            <%= b.text %>
          <% end %>
        </div>
      <% end %>

When I wrote out the html without the form builder object it displayed the check box in style just fine.
Have you run into this problem before or know a fix?

-Thanks
