@Inject does not work inside annotated class @Scheduled

I'm creating a class using deltaspike and quartz, using @scheduled. In this Injection class a CDI bean, which is a class of service. I chose to use deltaspike because it controls the context of the CDI within classes that use quartz. The bean, however, is not injected, being null. No exception is thrown on the console. The code does not appear or be called. But removing all the code from the method, removing @Inject and leaving only the log calls, works perfectly. What might be missing configure for dependency injection to work? Follow the code below.

@Scheduled(cronExpression = "0 0/1 * * * ?")
public class NotificacaoAgendaJob implements Job {
    Logger logger = Logger.getLogger("br.com.nutrierp.scheduler");

    @Inject
    AgendaService agendaService;

    public void execute(JobExecutionContext context) throws JobExecutionException {
        try {
            logger.info("Iniciando Job...");
            List<Agenda> agendas = agendaService.todasAgendasDoSistema();

            for (Agenda agenda : agendas) {
                LocalDateTime dataAgendada = agenda.getDataInicial();
                LocalDateTime dataAtual = LocalDateTime.now();
                Duration intervalo = Duration.between(dataAtual, dataAgendada);

                if (intervalo.toHours() <= 24 && intervalo.toHours() > 0) {
                    agendaService.enviarEmailDeNotificacao(agenda);
                }
            }
            logger.info("Finalizando Job...");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

After reading the deltaspike documentation again, I noticed that the beans are not injected because the annotated class with @scheduled is instantiated outside the context of the CDI. I used a CDIServiceLocator.

@Scheduled(cronExpression = "0 0 2 1/1 * ?")
public class NotificacaoAgendaJob implements Job {
    Logger logger = Logger.getLogger(NotificacaoAgendaJob.class.getName());

    SistemaService sistemaService;

    public void execute(JobExecutionContext context) {
        try {
            sistemaService = CDIServiceLocator.getBean(SistemaService.class);

            logger.info("Iniciando Job...");
            List<Agenda> agendas = sistemaService.todasAgendasDoSistema();

            for (Agenda agenda : agendas) {
                LocalDate dataAgendada = agenda.getDataInicial().toLocalDate();
                LocalDate dataAtual = LocalDateTime.now().toLocalDate();
                long intervalo = dataAgendada.toEpochDay() - dataAtual.toEpochDay();

                if (intervalo == 1) {
                    sistemaService.enviarEmailDeNotificacao(agenda);
                    logger.info("Enviando e-mail para " + agenda.getPaciente().getEmail());
                }
            }
            logger.info("Finalizando Job...");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

CDIServiceLocator

public class CDIServiceLocator {

    @SuppressWarnings("unchecked")
    public static <T> T getBean(Class<T> clazz) {

        BeanManager bm = CDI.current().getBeanManager();

        Bean<T> bean = (Bean<T>) bm.getBeans(clazz).iterator().next();
        CreationalContext<T> ctx = bm.createCreationalContext(bean);
        T targetBean = (T) bm.getReference(bean, clazz, ctx);

        return targetBean;
    }

}

Using this CDIServiceLocator, all dependencies of all classes involved, including entity managers, will be resolved.
