I want to execute javascript function after bean actionListener.I am using JSF 1.2, richfaces 3.3.In my case I want to display a chart after finishing bean's method.My table tabis filling but the javascript function didn't work. This is my attempt :

<h:form>
<h:commandButton value="Click" actionListener="#{bean.monActionListener}" reRender="tab">
<a4j:support event="onClick" oncomplete="show()" />
</h:commandButton>
<h:form>

<h:form id="sortie">
<rich:dataTable id="tab" rendered="#{not empty bean.listSortie}" 
value="#{bean.listSortie}" var="raison">

<h:column headerClass="headerleftfacet">
    <h:outputText value="#{raison[0]}">
    </h:outputText>
</h:column>
<h:column headerClass="headermiddlefacet">      
    <h:outputText  value="#{raison[1]}" >
    </h:outputText>
</h:column>

</rich:dataTable>
