Update JSF only works on whole form (Primefaces)

Navigation

Good evening. I'm breaking my head with a problem that seemed simple

I have a form with some fields, while selecting a combobox I want to hide and display some fields. I'm using 'p: ajax' to run the update.

And in the fields to hide, I'm using 'rendered'.

Everything works perfectly if I run the command: 

<p:ajax update="frmCad" event="change" />

This practice is not legal because it always resets all other fields that will already be filled. However, if I set the specific field to update, it does nothing. In case it would be: 

<p:ajax update="pam:lblSexo" event="change" />

Could someone give me a light?

In short, my code is as follows: 

<h:form id="frmCad" prependId="false">
  <p:accordionPanel id="pam" multiple="true" activeIndex="0,1">
    <p:tab id="tbCad" title="Cadastro" >
      <h:panelGrid id="gp1" columns="3" columnClasses="primeiraColumnP">

      <h:outputLabel id="lblSegPessoa" for="id" value="Pessoa: " styleClass="estilolabelCampos" />
      <p:selectOneRadio id="optTipo" value="#{pessoaBeanView.objetoSelecionado.pes_tipo_pessoa}">
        <f:selectItem itemLabel="Física" itemValue="Fisica" />
        <f:selectItem itemLabel="Jurídica" itemValue="Juridica" />
        <p:ajax update="pam:lblSexo" event="change" />
      </p:selectOneRadio>

  <p:outputLabel id="lblSexo" value="Sexo: " rendered="#{pessoaBeanView.objetoSelecionado.pes_tipo_pessoa == 'Fisica'}" />

...fechamentos>

Thanks for the help.

The update will only work if the lblSexo component is rendered. Try to make the following change: 

(...)

<p:ajax update="pnlSexo" event="change" />

(...)

<h:panelGroup id="pnlSexo">
    <p:outputLabel id="lblSexo" value="Sexo: " rendered="#{pessoaBeanView.objetoSelecionado.pes_tipo_pessoa == 'Fisica'}" />
</h:panelGroup>
