Bug in postSubmit, submitSuccess events

Good morning Allan,

this code isn't working any longer with the "create" action. It used to work with previous Editor versions but not any longer.

.on( 'postSubmit', function ( e, json, data, action ) {
    if ( action === 'edit' || action === 'create' ) {
        var selected = contractTable.row( {selected: true} );
        if (selected.any()) {
            $.ajax({
                type: "POST",
                url: 'actions.php?action=generateCashFlow',
                data: {
                    table: 'variable',
                    id: json.data[0].DT_RowId.substring(4), //only after "row_"
                    contractId: selected.data().contract.id
                }
            });
        }
    }
    ajaxReloadTbls( [contractTable, cashFlowTable] );
});

with the "create" action json.data is an empty array; no DT_RowId, nothing... I also tried this with the submitSuccess event. Same issue. It works fine with the "edit" action. Could you provide a fix please. Many thanks.
