title: Icon tag <i> in remote ajax call in rails
body: <p>i want to use the new Icon  tag from bootstrap css to make a remote call in rails 3.1.1</p>
  
  <p>Here is my original code:</p>
  
  <pre><code>&lt;%=link_to(image_tag("/assets/icons/sub_blue_down.png", :class =&gt; "points_arrow"),        
  vote_down_politician_path(pending_discussions, :politician_id  =&gt;   
  pending_discussions.politician_id), :remote=&gt; true, :method =&gt; :post) %&gt;
  </code></pre>
  
  <p>I want to use this:</p>
  
  <pre><code>&lt;i class="icon-minus-sign"&gt;&lt;/i&gt;
  </code></pre>
  
  <p>Instead of the image tag</p>
  
  <p>Here is my attempt but doesn't work:</p>
  
  <pre><code>&lt;%= link_to  ' &lt;i class="icon-plus-sign"&gt;&lt;/i&gt;', 
  vote_up_politician_path(pending_discussions, :politician_id  =&gt;    
  pending_discussions.politician_id), :remote=&gt; true, :method =&gt; :post%&gt;
  </code></pre>
