[jQuery] An issue with .clone(true) and IE 6+

Hi everybody,
I'm sorry for my English...
I'm trying to add a new table row (<tr>) after an ajax call.
My code works perfectly with FF or Opera, but not with IE.
With the right browsers I can add multiple row, IE instead overwrite
my first row (with right content but overwrite the last inserted).
This is my code after an ajax call which insert a new record in a DB
table:
function processJson(data) {
// 'data' is the json object returned from the server
        $("#responceRow").clone(true).prependTo("#dataTables");
        $("#addImage").html('<a href="<?=site_url('admin/settings/
select_typologies_options')?>/'+ data.newId+'"></a>');
        $("#responceRow").fadeIn();
        $("#newId").html(data.newId);
        $("#newName").html(data.newName);
        $("#newUrl").html(data.newUrl);
        $("#newCreated").html(data.newCreated);
        $("#newLastedit").html(data.newLastedit);
        $("#newStatus").html(data.newStatus);
}
</script>
[...]
<tr id="responceRow">
    <td class="tableCellNew" id="newId"> </td>
    <td class="tableCellNew" id="newAdd">
    <div id="addImage">
    <?='<span>' . $this->lang->line('actionAddDetails') . '</span>'?>
    </div>
    </td>
    <td class="tableCellNew" id="newName"> </td>
    <td class="tableCellNew" id="newUrl"> </td>
    <td class="tableCellNew" id="newCreated"> </td>
    <td class="tableCellNew" id="newLastedit"> </td>
    <td class="tableCellNew" id="newStatus"> </td>
    <td class="tableCellNew" id="newCheckbox">
    <input class="checkbox" type="checkbox" name="toggle[]" />
    </td>
</tr>
Have u any idea?
Many Thanks
