setHtml with cke_protected not working in IE

Hello girls and guys,

I try to save a javascript snipped after leaving a dialog. It worsk in Chrome and FF but not IE7. It seams somehow the data is not stored inside innerHTML.

The code:

onOk : function()
{
    var videoNode = null;
  
    if ( !this.fakeImage ) {
        videoNode = CKEDITOR.dom.element.createFromHtml( '<cke:video></cke:video>', editor.document );
    }
    else
    {
        videoNode = this.videoNode;
    }

    var extraStyles = {}, innerHTML;
    this.commitContent( videoNode, extraStyles );
  

    innerHTML = '<!--{cke_protected}' + encodeURIComponent(
    '<script language="JavaScript" type="text/javascript">\n' + 
        '        $(document).ready(function() {\n' + 
        "            jwplayer('" + videoNode.getAttribute('id') + "').setup( configCKEditor('" + videoNode.getAttribute('src') + "', " + videoNode.getAttribute('width') + ", " + videoNode.getAttribute('height') + ") );\n" +
        '        });\n' +
        '</script>') + '-->';

    videoNode.setHtml( innerHTML );
            
    // Refresh the fake image.
    var newFakeImage = editor.createFakeElement( videoNode, 'cke_video', 'video', false );
    newFakeImage.setStyles( extraStyles );
    if ( this.fakeImage )
    {
        newFakeImage.replace( this.fakeImage );
        editor.getSelection().selectElement( newFakeImage );
    }
    else
        editor.insertElement( newFakeImage );
},

Somehow the problem occurs inside

videoNode.setHtml( innerHTML );

Could you help me?
