JSF + Primefaces p: selectOneRadio within Datatable and Pagination

<p:dataList value="#{simuladoBean.questoes}" var="q" type="unordered"
                rowIndexVar="qi" itemType="none" paginator="true" rows="1"
                styleClass="paginated">

      <h:panelGrid columns="2" style="color:#000;"
                        rendered="#{q.tipo == simuladoBean.certoErrado}">
                        <p:outputLabel for="resposta" value="Resposta: " />
                        <p:selectOneRadio id="resposta" value="#{simuladoBean.resposta}"
                            style="color:black;width:auto;">
                            <p:ajax listener="#{simuladoBean.processaResposta}" />
                            <f:selectItem itemLabel="Certo" itemValue="Certo | #{q.id}" />
                            <f:selectItem itemLabel="Errado" itemValue="Errado | #{q.id}" />
                        </p:selectOneRadio>
     </h:panelGrid>
            </p:dataList>

My ManagedBean is as @Named and @ViewScoped .

import javax.inject.Named;
import javax.faces.view.ViewScoped;

The code works normally, but when I go from page to page (Pagination), when I return to the previous page, radiobutton is unchecked, ViewScoped does not work for SelectOneRadio . How do I keep Selectoneradio as viewScoped , so that it is marked for example right on the first page when moving to the second and returning to the first one the 'right' is still marked?
