Adding an Element not working (rails)

I'm blocked on this since 3 days : Here is my view :

<h1>Liste des livres</h1>

<% @books.each do |book| %>

  <p><a href="/books/<%= book.id %>"><%= book.title %></a></p>

<% end %>

<%-# Adding a book %>

<%= form_tag "/books", method: "post" do %>
  <input type="text" name="title" />
  <input type="submit" value="Ajouter le livre" />
<% end %>

And here is the controller :

class BooksController < ApplicationController
  def index
    @books = Book.all
  end

  def create
    Book.create title: params[:title]
    redirect_to "/books"
  end

  def show
    @book = Book.find(params[:id])
  end

  def update
    Book.find(params[:id]).update title: params[:title]
    redirect_to "/books/#{params[:id]}"
  end

  def destroy
    Book.find(params[:id]).destroy
    redirect_to "/books"
  end

end

Finally my routes :

Rails.application.routes.draw do
  get 'pages/home'
  get 'books/index'
  get 'books' => 'books#index'
  post 'books' => 'books#index'
  get 'books/:id' => 'books#show'
  patch 'books/:id' => 'books#update'
  delete 'books/:id' => 'books#destroy'

Now when i insert a book name and click on the button i see this in the terminal :

Started POST "/books" for 127.0.0.1 at 2016-02-17 15:38:39 +0100
Processing by BooksController#index as HTML
  Parameters: {"utf8"=>"✓", "authenticity_token"=>"TgLJMVchOq/3yKT2cii82ywS6qNVH8xI9E4mMnuNeI/BK/5SXnRosM0+mKwDlxOEO3WtEg5zttU7Tx69YYJkKQ==", "title"=>"ahah"}
  Book Load (0.2ms)  SELECT "books".* FROM "books"
  Rendered books/index.html.erb within layouts/application (1.3ms)
Completed 200 OK in 27ms (Views: 26.2ms | ActiveRecord: 0.2ms)

But when the pages has refreshed nothing is added and if i open another terminal window and i check in a rails console with Book.all there is nothing more then the original list of books. Is there something wrong with my code ?

In your routes your post request should point to the create action.

So it should look like this: post 'books' => 'books#create' not post 'books' => 'books#index'
