Clear form after registration (Javaserver Faces)

Question

After having made a registration, it clears the form normally, but when I change page and return to the registration page, the fields are filled with the values I previously registered. The scoped I’m using is @Viewscoped.

Registration page..

<ui:define name="content">
    <h1 class="aw-page-title">Realizar Emprestimos</h1>

    <h:form id="form" prependId="false">

        <p:messages id="msgs"/>

        <p:toolbar>
            <f:facet name="left">
                <p:toolbarGroup>
                    <p:commandButton value="Confirmar" action="#{empMB.inserir}" process="@this"
                    update="form:list_publicacao" ajax="false">
                        <f:ajax render="form:list_publicacao" resetValues="true"/>
                    </p:commandButton>
                </p:toolbarGroup>
            </f:facet>

            <f:facet name="right">
                <p:toolbarGroup>
                    <p:commandButton value="Cancelar" action="#{empMB.limparCampos()}"
                    immediate="true">
                        <f:ajax render="@form" resetValues="true"/>
                    </p:commandButton>
                </p:toolbarGroup>
            </f:facet>
        </p:toolbar>
    <f:ajax event="blur">
        <h:panelGrid id="p1" columns="4" layout="grid">

                    itemValue="#{usu.idUsuario}" itemLabel="#{usu.nomeUsuario}" />
            </p:selectOneMenu>

            <p:outputLabel value="Data Emprestimo: " for="dataEmprestimo" />

Method..

public Emprestimo inserir() {
    System.out.println(getListPublicacaoDesejada().size());
    try {
        for (int i = 0; i < getListPublicacaoDesejada().size(); i++) {
            Calendar dataPrevista = Calendar.getInstance();
            dataPrevista.setTime(emprestimo.getDataEmprestimo());
            dataPrevista.add(Calendar.DAY_OF_MONTH,
                    Integer.parseInt(JSFHelper.getExternalContext().getInitParameter("previsaoDevolucao")));
            emprestimo.setFuncionarioEmprestimo("usuarioteste08");
            emprestimo.setDataPrevistaDevolucao(dataPrevista.getTime());
            emprestimo.getPublicacao().setPublicacaoId(emprestimo.getListPublicacao().get(i).getPublicacaoId());
            emprestimoFacade.inserir(emprestimo);
        }
        FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_INFO, "Emprestimo(s)", "realizado(s) com sucesso!");
        RequestContext.getCurrentInstance().showMessageInDialog(message);
        emprestimo = new Emprestimo();
        return emprestimo;
    } catch (DAOException e) {
        e.printStackTrace();
        FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_INFO, "Atenção", "Erro ao realizada emprestimo");
        RequestContext.getCurrentInstance().showMessageInDialog(message);
        return null;
    }
}

In your Bean implement the Postconstruct that is called when starting your page.

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