title: render update and replace_html not working in rails 4
body: <p>Currently  i am upgrading my app to rails 4 and using RJS in many places.
  later on i cames to know that RJS removed and its still available through prototype-rails gem .so that I have added the gem and included in applicaton.js,but still I am getting the same issue.</p>
  
  <pre><code>ActionView::MissingTemplate (Missing template lease/update, application/update with {:locale=&gt;[:en], :formats=&gt;[:js, :html, :xml, :html, :text, :js, :css, :ics, :csv, :png, :jpeg, :gif, :bmp, :tiff, :mpeg, :xml, :rss, :atom, :yaml, :multipart_form, :url_encoded_form, :json, :pdf, :zip], :handlers=&gt;[:erb, :builder, :raw, :ruby, :rjs]}

  <pre><code>def ajax_refer
   render :update do |page|
              page.replace_html  "lease_container", :partial =&gt; "/lease/property_pipeline", :locals =&gt; {:note_collection =&gt; @note, :portfolio_collection =&gt; @portfolio_collection}
  end
  end
