<%= f.submit %> doesn't send the params to Controller.( Ruby On Rails )

I made this simple form:

<%= form_for @recipe do |f| %>
    <%= f.text_field :title, name: 'Título' %>
    <%= f.text_field :recipe_type, name: 'Tipo da Receita' %>
    <%= f.text_field :cuisine, name: 'Cozinha' %>
    <%= f.text_field :difficulty, name: 'Dificuldade' %>
    <%= f.text_field :cook_time, name: 'Tempo de Preparo' %>
    <%= f.text_area :ingredients, name: 'Ingredientes' %>
    <%= f.text_area :cook_method, name: 'Como Preparar' %>
    <%= f.submit :submit, name: 'Enviar %>
<% end %>

But when I submit it, I get this error:

 Failure/Error: params.require(:recipe).permit(:title, :recipe_type, :cuisine, :difficulty, :cook_time, :ingredients, :cook_method)

     ActionController::ParameterMissing:
       param is missing or the value is empty: recipe
     # ./app/controllers/recipes_controller.rb:23:in `recipe_params'
     # ./app/controllers/recipes_controller.rb:16:in `create'
     # ./spec/features/user_register_recipe_spec.rb:18:in `block (2 levels) in <top (required)>'

The problem is in the submit button, I need it named Enviar, but I tried every possible combination and nothing works. I tried:

<%= f.button :submit %>      Unable to find link or button "Enviar"
<%= f.submit 'Enviar' %>     I get the error of missing params
<%= f.submit :submit, name: 'Enviar' %> Unable to find link or button "Enviar"

I don't know what to do anymore. Here my Controller:

class RecipesController < ApplicationController

  def index
    @recipes = Recipe.all
  end

  def show
    @recipe = Recipe.find(params[:id])
  end

  def new
    @recipe = Recipe.new
  end

  def create
    @recipe = Recipe.new(recipe_params)
    if @recipe.save
      redirect_to recipe_path(@recipe)
    else 
      render :new
    end
  end

  private
    def recipe_params
      params.require(:recipe).permit(:title, :recipe_type, :cuisine, :difficulty, :cook_time, :ingredients, :cook_method)
    end

end

My router:

Rails.application.routes.draw do
  root to: 'recipes#index'
  get 'recipes/new' => 'recipes#new', as: 'new_recipe'
  post 'recipes/new' => 'recipes#create'
  resources :recipes
end

Edit: (Error when can't find the button)
