How to set values into a selectradiobutton from a managed bean? - jsf

Question

I´ve a datatable that has a column with selectoneradio, so I´m supposed to turn on the radios if they are on in my database. So I recover my data but I can´t figured how to tell my selectoneradio buttons to be on when my users consult the page with the table. Here is the code from my table:
<p:dataTable id="secciones" var="secciones" value="#{seccionesMB.seccionesList}" style="width: 60%;">
<p:column>
<f:facet name="header">
<h:outputText value="" />
</f:facet>
<h:outputText value="#{secciones.codigo}" />
<f:facet name="header" >
<h:outputText value="Seccion" />
</f:facet>
<h:outputText value="#{secciones.seccion}" />
</p:column>
<p:column>
<f:facet name="header">
<div align="left"> <h:outputText value="Alta Baja Consulta Mod N/A" /></div>
</f:facet>
<p:selectOneRadio id="options" value="#{secciones.nivel}" disabled="true">
<f:selectItem itemLabel="10000" itemValue="10000" />
<f:selectItem itemLabel="01000" itemValue="01000" />
<f:selectItem itemLabel="00100" itemValue="00100" />
<f:selectItem itemLabel="00010" itemValue="00010" />
<f:selectItem itemLabel="00001" itemValue="00001" />
</p:selectOneRadio>
</p:column>
</p:dataTable>
and here is the method from my backing bean that feeds my datatable:
public String consultarPerfil(int id, String perfil) {
this.setId(id);
this.setPerfil(perfil);
try {
List<Perfiles_Secciones> list = getPerfiles_SeccionesService().getPerfiles_Seccion(id);
int i = 0;
for(SeccionesDTO seccionDTO : seccionesList) {
for(Perfiles_Secciones ps : list) {
if (seccionDTO.getId() == ps.getId_seccion()) {
System.out.println(seccionDTO.getId() + " - " + ps.getId_seccion());
seccionDTO.setNivel(ps.getNivel());
}
i++;
}
i = 0;
}
for(SeccionesDTO seccionDTO : seccionesList) {
System.out.println(seccionDTO.getNivel());
}
} catch (Exception ex) {
Logger.getLogger(PerfilesManagedBean.class.getName()).log(Level.SEVERE, null, ex);
}
return CONSULTAR_PERFIL;
}
What do I need to do in order to feed my selectoneradio from my managed bean??
