title: Rails 2 to Rails 3 : using link_to instead of link_to_remote (including remote and update)
body: <p>A quick and easy answer I'm sure. 
  I'm upgrading a Rails project from version 2 to version 3 and replacing a load of the link_to_remote with link_to's as per the Rails 3 update. Even something as simple as :</p>
  
  <pre><code>&lt;%= link_to "Check Time",
          {:action=&gt;:get_time}, :remote=&gt;true, :update=&gt;'current_time' %&gt;
  &lt;div id='current_time'&gt;&lt;/div&gt;
  </code></pre>
  
  <p>doesn't seem to work. The request (using get method) is going through ok and the rendered html is :</p>
  
  <pre><code>&lt;a href="/monitoring/get_time" data-remote="true" update="current_time"&gt;Check Time&lt;/a&gt; 
  </code></pre>
  
  <p>Routes.rb entry :   </p>
  
  <pre><code>get "monitoring/get_time"
  </code></pre>
  
  <p>As I say I'm sure this is a very obvious issue on my part!</p>
