p: dialog being called by several buttons in the system

Personnel I have a dialog (of primefaces ) that confirms the number of CEP and after the user to inform the number of the residence in this dialog the fields address, neighborhood, cep, city and uf have to be filled in the form . The problem is that this dialog can be called in several places of the system where they have CEP to validate, in the same form if they have more than one CEP. So how do I get the Confirm button from dialog to execute different methods and beans different?

PS: I'm using JSF+PrimeFaces .

Follow the code:

Dialog:

The ClienteMB that controls the form and calls the CepMB that shows the dialog:

public void buscaCEPRes() {
     cepMB.confirmaCEP(cliSel.getCep(), cliSel.getEndereco(), cliSel.getCidade(), cliSel.getUf());
}

public void buscaCEPCom() {
     cepMB.confirmaCEP(cliSel.getEmpCep(), cliSel.getEmpEndereco(), cliSel.getEmpCidade(), cliSel.getEmpUf());
}

The CepMB controls the dialog with the zip search:

    public void confirmaCEP(String nrCEP, String valEndereco, String valCidade, String valUf) throws IOException,IllegalArgumentException {
        ViaCEPClient client = new ViaCEPClient();
        viaEndereco = null;
        listaViaEndereco = null;
        okCEP = false;
try{
        if (StringUtils.isNotBlank(nrCEP)){   
           viaEndereco = client.getEndereco(nrCEP);
if (endereco != null) {carregaEnderecoParaConfirma();
}else{createFacesErrorMessage("CEP Inválido", "Não Foi Possível Localizar CEP!");}
   }else{ if (!StringUtils.isNotBlank(valCidade)||!StringUtils.isNotBlank(valUf)){
    createFacesErrorMessage("Dados Inválidos", "É Necessário Informar no Mínimo a Cidade e o Estado!");
}else{
     listaViaEndereco = client.getEnderecos(valUf, valCidade, valEndereco);
  if (listaViaEndereco != null) {carregaListaEnderecoParaConfirma();
}else{createFacesErrorMessage("Endereço Inválido", "Não Foi Possível Localizar CEP!");}
    }
}
 }catch (IOException e){
   createFacesErrorMessage("Erro I/O", "Não Foi Possível Conectar com o Servidor de CEP!");  
 }catch (IllegalArgumentException e){
        createFacesErrorMessage("CEP Inválido", e.getMessage());
 }


    }

public void carregaEnderecoParaConfirma(){
    endereco = viaEndereco.getLogradouro();
    bairro = viaEndereco.getBairro();
    nrComp = "";
    RequestContext.getCurrentInstance().update("form:cepConfirmPanel");
    RequestContext.getCurrentInstance().execute("PF('cepConfirmDlg').show();");
    }    

The method of the Confirm dialog button did not do it.
