title: simple_form error notifications not displaying using zurb foundation
body: <p>I am using Zurb Foundation and Simple form</p>
  
  <pre><code>&lt;%= simple_form_for @complaint do |f| %&gt;
     &lt;%= f.error_notification %&gt;
  
     &lt;%= f.association :company, as: :radio, label: false %&gt;
     &lt;%= f.input :country, priority: ["United States"] %&gt;
     &lt;%= f.input :city %&gt;
     &lt;%= f.input :client, placeholder: 'Coca-Cola' %&gt;
     &lt;%= f.input :body %&gt;
  
     &lt;%= f.button :submit %&gt;
  &lt;% end %&gt;
  </code></pre>
  
  <p>In my model:</p>
  
  <pre><code>class Complaint &lt; ActiveRecord::Base
    belongs_to :company
    attr_accessible :body, :city, :client, :country, :company_id
    validates :company, presence: { message: 'Company cannot be blank!' }
    validates :body, presence: true
    validates :country, presence: true
    validates :city, presence: true
  end
  </code></pre>
  
  <p>When I click submit on an empty form I expect to have errors saying 'Company cannot be blank!' etc.</p>
  
  <p>Am I using <code>&lt;%= f.error_notification %&gt;</code> incorrectly?
  How can I get there to show errors?</p>
