title: remember me not working simple form
body: <p>I am using Devise for authentication. Trying to edit/create devise forms with simple_form.</p>
  
  <p>this </p>
  
  <pre><code>&lt;%= simple_form_for(resource, :as =&gt; resource_name, :url =&gt; session_path(resource_name), :html=&gt;{:class=&gt;"form-vertical"}) do |f| %&gt;
  &lt;%= f.input :email, :placeholder=&gt;"Email", :label=&gt;false %&gt;
  &lt;%= f.input :password, :placeholder=&gt;"Password", :label=&gt;false %&gt;
  
  &lt;% if devise_mapping.rememberable? -%&gt;
      &lt;div style="display:inline"&gt;&lt;%= f.input :remember_me, :inline_label =&gt; 'Yes, remember me'%&gt;&lt;/div&gt;
  
  &lt;%end -%&gt;
      &lt;div&gt;&lt;%= f.submit "Sign in", :class=&gt;"pull-right btn btn-primary" %&gt;&lt;/div&gt;
  &lt;div&gt;&lt;%= link_to "Create an account", new_user_registration_path%&gt;&lt;/div&gt;
  &lt;% end %&gt;
  </code></pre>
  
  <p>is literally giving me; <strong>Remember Me</strong>, which should be checkbox</p>
