how to subscribe a user to a Mailchimp list using Gibbon on Rails

Question

I'm trying to subscribe users to a mailchimp, not sure if i'm making an error on the form or the controller , I followed some tutorials online but haven't had no luck.

I'll appreciated any help thank you

Here is my view using a form_tag

<h1>Newsletter subscribe</h1>
<p>Sign up for email  updates</p>
<%= form_tag('subscribenow', method: "post", id: "subscribe", remote: "true") do %>
   <%= email_field(:email,:address, {id: "email", placeholder: "email address"}) %>
   <%= submit_tag("Sign me up!") %>
<% end %>

this is my controller

class EmailapiController < ApplicationController
def index
end

 def subscribe

    list_id = "my_id"
    gb = Gibbon::API.new

    gb.lists.subscribe({:id => list_id,
                        :email => {:email => 'email_address'}, 
                        :merge_vars => {:FNAME => 'First Name', 
                        :LNAME => 'Last Name'},             
                        :double_option => false})
 end
end

(these are my routes on the routes.rb file)

get 'emailsignup'  => 'emailapi#index'
post 'subscribenow'=> 'emailapi#subscribe'

my initializer file

  Gibbon::API.api_key = "my_api_key"
  Gibbon::API.timeout = 15
  Gibbon::API.throws_exceptions = false

This is the error I get on my local server
