JSF h:commandButton is not working inside h:DataTable - jsf

Question

I'm trying to delete a specific data in a table, i try to get the column id by using commandButton but it doesn't work, i tried to just show a message in the console when the button is clicked but no luck at all, i tried also some solutions that were offered in this community but it didn't work for me.
Ps: i tried to use ViewScoped instead of request, but it didnt work too.
Here is a part of my code:
<f:view>
<h:form>
<h:commandButton
value="Afficher les demandes"
action="#{demandeBean1.listedemandes}"
styleClass="btn btn-success" />
</h:form>
<h:form>
<h:dataTable
value="#{demandeBean1.demandes}"
var="demande"
styleClass="table table-bordered"
cellspacing="4"
width="60%"
rowClasses="paire,impaire"
headerClass="titre">
<h:column>
<f:facet name="header">
<h:outputText value="Date de demande" />
</f:facet>
<h:outputText value="#{demande.dateDmd}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Date de debut" />
</f:facet>
<h:outputText value="#{demande.dateDbtAbs}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Date de fin" />
</f:facet>
<h:outputText value="#{demande.dateFinAbs}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Nombre de jours" />
</f:facet>
<h:outputText value="#{demande.nbrJr}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Type" />
</f:facet>
<h:outputText value="#{demande.type}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Status" />
</f:facet>
<h:outputText value="#{demande.status}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Action" />
</f:facet>
<h:commandButton
value="Supprimer"
styleClass="btn btn-danger"
actionListener="#{demandeBean1.supprimer(demande.idDmd)}">
</h:commandButton>
</h:column>
</h:dataTable>
</h:form>
</f:view>
My Bean:
#Named
#RequestScoped
public class DemandeBean implements Serializable {
private int idDmd;
private Date dateDbtAbs;
private Date dateDmd;
private Date dateFinAbs;
private int nbrJr;
private String status;
private String type;
private List<Demande> demandes;
public DemandeBean() {}
public void supprimer(int id) {
System.out.println("It works"); //this is not displaying
}
}
