I am trying to automatically reRender a datatable when user click on the Ok button on a modal panel. For whatever reason it isn't refreshing. What am I doing wrong here? Any help will be greatly appreciated.

<h:form>  
    <rich:dataTable id="promoList" columnClasses="column" 
       value="#{Promotions.promotionList}" var="promoDetail" rows="20">  
  
        <rich:column sortBy="#{promoDetail.promotion.promoName}">  
            <f:facet name="header">Promotion Name</f:facet>  
               <h:commandLink action="#{AddPromotion.editPromotionAction}" 
                              actionListener="#{AddPromotion.gotoPromotionTab}" 
                              value="#{promoDetail.promotion.promoName}">  
                      <a4j:actionparam name="promotionId" 
                              value="#{promoDetail.promotion.id}" 
                              assignTo="#{AddPromotion.promotionId}"/>
               </h:commandLink>  
        </rich:column>  
                  
        <rich:column>  
           <f:facet name="header">Price</f:facet>  
            <h:outputText value="#{promoDetail.promotion.suggestedPrice}" />  
         </rich:column>  
       </rich:dataTable>  
</h:form>  
  
  
 <rich:modalPanel id="deleteStatusPanel" width="350" height="150">  
     <f:facet name="header">  
        <h:outputText value="Delete Promotion" />  
     </f:facet>  
     <h:panelGroup>  
        <h:form>  
           <center>  
           <rich:spacer height="15" />  
           <h:panelGrid columns="1">  
              <h:outputText style="white-space:normal" 
                            value="#{Promotions.deletePromoStatus}" />  
           </h:panelGrid>  
           <rich:spacer height="30" />  
           <a4j:commandButton value="OK" 
           onclick="Richfaces.hideModalPanel('deleteStatusPanel');" 
           reRender="promoList"/>  
           </center>  
        </h:form>  
    </h:panelGroup>  
 </rich:modalPanel>
