The tablename was missing in the button_callback.
Without the tableName you cannot write generic callbacks mit permission-check etc.
Obviously there are some more parameters in the core button_callback ($arrRootIds, $arrChildRecordIds, $blnCircularReference, $strPrevious, $strNext, $this). But they are not so easy available in the dcaWizard and for normal generic callbacks not necessary.
