Render HTML inside block - Ruby on Rails

I'm trying to render a HTML with a partial inside of a block but the only thing that renders are the last 4 closing </div> elements.

Here is my code:

<%= new_item_modal do |i| %>
<div class="modal fade" id="newItemModal" tabindex="-1" role="dialog" aria-labelledby="newItemModal" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title">New Item</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body" id="new-item" style="overflow:scroll;height:500px;">
        <%= render partial: "/items/form", locals: { remote: true, item: @item, categories: @categories }%>
      </div>
    </div>
  </div>
</div>
<% end %>

And my new_item_modal function:

def new_item_modal(&block)
   if current_location.present? && can_access("create", "items")
      @item = Item.new
      @categories = current_location.categories
      block.call
   end  
end

Your first line should read <%= new_item_modal do |item, categories| %> <%= new_item_modal do |item, categories| %> and your new_modal_item method should have block.call(@item, @categories) . Make sure you rename the variables passed to the partial (for example, from @item to item ).
