primefaces - P:ajax not working with p:commandbutton -


i try never work ;why ajax not supported ??

<p:commandbutton value="maj" rendered="#{lignexl.resultat eq 'pas de fmd'}" onclick="confirmation.show()"  >     <f:setpropertyactionlistener target="#{parserxls.selectitem}" value="#{lignexl}" />                       <p:ajax event="click" listener="#{parserxls.listenercomposant()}"/>              </p:commandbutton>

listener never executed why !!! i'm trying object according selectitem

public void listenercomposant(){     composantitem=cherchercomposant(selcetitem.getrefcomposant(), selcetitem.getreffabricant()); }

the command button ajax based. need have like

  <p:commandbutton value="testbutton" actionlistener="#{bean.savesomething}" id="id"       update="panel" />

as can see commandbutton has actionlistener use that.
