Creating dialog using CQ.Util.build

Hi

       After referring Entryform.jsp in blog component in libs , i tried a code bit

<div id= 'new'>

    </div>

    <script type="text/javascript">

    CQ.Util.build({

        "xtype":"panel",

        "border":false,

        "layout":"form",

        "defaults": {

            "hideLabel":true

        },

        "items":[{

            "xtype":"textfield",

            "defaultValue":"Entry title",

            "fieldLabel":"title",

            "name":"title"

        }

        ,{

            "xtype":"richtext",

            "name":"text",

            "width":"100%",

            "enableSourceEdit":true,

                "fieldLabel":"richtext"

        }

    ],

    "renderTo":"new"

    });

    </script>
