remove row from datatable

remove row from datatable

Hi, I need some help I don't know how to remove a row from datatable.
This my xhtml file:
<p:commandButton id="confirm" value="Valider" update=":messages"
oncomplete="dialogdelete.hide()"
actionListener="#{agentBean.btnDelete}"
styleClass="ui-confirmdialog-yes"
icon="icon-ok"/>
Session bean:
public void delete (Agentministere agentministere) {
agentministereFacade.remove(agentministere);
}
Managed Bean:
public String btnDelete (){
manager.delete(agentministere);
return "AgentList";
}
