Primary sorting and filtering of data does not work until rowSelect

I know this question can be duplicated, but I really cannot find a solution to my problem; my problem is that the data processing functions, such as sorting and filtering, do not work, unless I click on any line to display the details dialog box after closing the dialog box, all “sorting, filtering” works fine and as expected.

here is my code: Bean.java

@ViewScoped
public class HomeBean implements Serializable {

    private List<Ticket>    filteredTickets;
    private List<Ticket>    tickets;
    private Ticket          selectedTicket;
    private Ticket[]        selectedTickets;

    public HomeBean() {
        super();
    }

    @PostConstruct
    public void init() {
        getData();
    }

    private void getData() {
        TicketFacade service;
        service = TicketFacade.getInstance();
        try {
            tickets = service.selectTickets();
        } catch (Exception e) {
            logger.error(Utilities.printStackTrace(e));
        }
    }
    // setter & getters

    @PreDestroy
    public void finalize() {
        logger.debug("@PreDestroy");
    }
}

And here is xhtml
