Rspec test fail

Right, so I'm trying to follow a long with sprining-Jason but seem to have hit a snag. I create the spec:

require 'spec_helper'

describe "Editing todo lists" do
    it "updates todo list successfully with correct information" do

        todo_list = TodoList.create(title: "Groceries", description: "Grocery list.")


        visit "/todo_lists"
        within "#todo_list_#{todo_list.id}" do
            click_link "Edit"
        end 

        fill_in "Title", with: "New Title"
        fill_in "Description", with: "New description"
        click_button "update Todo list"

        todo_list.reload

        expect(page).to have_content("Todo list was successfully updated.")
        expect(todo_list.title).to eq("New title")
        expect(todo_list.description).to eq("New description") 
    end
end 

The index HTML looks like this:

<p id="notice"><%= notice %></p>

<h1>Listing Todo Lists</h1>

<table>
  <thead>
    <tr>
      <th>Title</th>
      <th>Description</th>
      <th colspan="3"></th>
    </tr>
  </thead>

  <tbody>
    <% @todo_lists.each do |todo_list| %>
      <tr id="<%= dom_id(todo_list) %> " >
        <td><%= todo_list.title %></td>
        <td><%= todo_list.description %></td>
        <td><%= link_to 'Show', todo_list %></td>
        <td><%= link_to 'Edit', edit_todo_list_path(todo_list) %></td>
        <td><%= link_to 'Destroy', todo_list, method: :delete, data: { confirm: 'Are you sure?' } %></td>
      </tr>
    <% end %>
  </tbody>
</table>

<br>

<%= link_to 'New Todo list', new_todo_list_path %>

When I run the text in the terminal:

Failures:

When I look in the dev tools I see that the dom_id is incrementing from the last save. For example todo_list_6 and capybara is looking by default for todo_list_1. Hence the error.

I'm stumped. Any thoughts?
