$("#MyEditor).ckeditor(); do not work

Hallo,
i am started to use ckeditor. I like to use ckeditor with the jquery Adapter. The example at the developers Guide do not work. CKEditor will not displayed.

The following code i used:
html-File

<script type="text/javascript" src="/ckeditor/ckeditor.js"></script>
<script type="text/javascript" src="/ckeditor/adapters/jquery.js"></script>
...
...
<div id='divSelbstdarstellung' style='position:absolute; left:45px; top:550px; height:170px' align='left'>
<textarea id='Selbstdarstellung' name='Selbstdarstellung' readonly:'readonly' value=''></textarea></div>",

at the jqueryFile:

   $("#pshEdit_Selbstdarstellung").click(function(event) {
      $("#Selbstdarstellung").attr("readonly", "");
//      alert("Test");
      $('#Selbstdarstellung').ckeditor();
   });

So when the click-event fires, the ckeditor will not show.
I hope somone has an idee whats the problem?

Thanks for your answer
joachim
