hello I have a problem with the css styles jquerymobile

This is the function to imprimer results after clicking a button:

printResult function (olist) {

             innerHtmlText var = getHtml (olist);

         alert (innerHtmlText);

           IDIV var = $ (result). append (innerHtmlText);

         alert ("before refresca1" + IDIV);

         $ ('# result ul li'). listview ("refresh");

         alert ("after refresca3");

         }

Here the results are printed in a list in this layer

     <div id="result"> </ div>

     html printing is as follows

<a <li> href='index.html'> <img src = 'http://images.webcams.travel/thumbnail/1194624090.jpg' height = '12% 'width = '18%' / > <b> Caldones </ b> </ a> </ li> </ ul>

the result is displayed but the styles do not take. javascript instruction fails $ ('# result ul li'). listview ("refresh"), I've also tried with $ ('# result'). listview ("refresh"); useless

please someone help me?
