Add ID to TR element after row is dynamically added

Init is pretty much basic:

    $('#table-groups').dataTable( {
    "bJQueryUI": true,
    "sPaginationType": "full_numbers",
    "bFilter": false,
    "bInfo": false,
    "aLengthMenu": [[10, 25, 50, -1], [10, 25, 50, "All"]],
    "aoColumns": [
     { "sClass": "name" },
     { "sClass": "tools", "bSortable": false},
     ],     
    });

Now I have a server-side script that will return me Json like this:

{"response":"OK","entryid":"83","name":"Testinggroup"} 

Now I have a function that adds a row in DataTable

$('#table-groups').dataTable().fnAddData( ["<strong>"+$_returnvalue.name+"</strong>","<div class=\"cell edit\"><a href=\"manage-groups.php?group_id="+$_returnvalue.entryid+"\">Edit settings</a></div><div class=\"cell delete\"><a href=\"javascript:void(0)\" onclick=\"DeleteGroup(this,\'"+$_returnvalue.entryid+"\');\" class=\"delete\">Delete</a></div>"]);	

And all works well, but I need to add ID to the newly created <tr> element (id should be enrtryid that I have $_returnvalue.entryid )

Any ideas how to achieve this ?

Thanks a lot !
