fnGetPosition in 1.10.0-dev

"fnInitComplete": function () {
  $('#Test tbody tr').on('click', function () {
  var aPos = oTable.fnGetPosition(this);
  alert(aPos);
});

This code works fine in version 1.9.4, but in the version 1.10.0-dev works only for a page which is visible during initialization table. In other pages nothing happens and no errors. I'm doing something wrong? Thank you.
