title: issue using jquery.load() and url.Action using multiple parrameters
body: <p>i have the next function:</p>
  
  <pre><code>    $('#show-modal').click(function () {
          $('#my-dialog').load("@Url.Action("_BuscarPersona", "Persona", new { target = "#idtest", tipoPredefinido = 0 })", function () {
              $(this).dialog('open');
          });
      });
  </code></pre>
  
  <p>the problem im having is that utl.Action is changing the <code>&amp;</code> to <code>&amp;amp</code> on the url, so my controller wont find any method match.</p>
  
  <pre><code>http://localhost:3456/Persona/_BuscarPersona?target=%23idtest&amp;amp;tipoPredefinido=0
  </code></pre>
  
  <p>any know how to solve it?</p>
