a4j commandLink not working with in a4j repeat

[krish_nyk]

Here is my code :

       <a4j:repeat ......>

       <rich:datatable>

       <rich:column>

           <a4j:commandLink value="Edit" action="#{poReceiptBean.testMethod()}"

            actionListener="#{poReceiptBean.addRowListener}" oncomplete="#

             {rich:component('editReceiptModal')}.show();"></a4j:commandLink>

       </rich:column>

       </rich:datatable>

       </a4j:repeat>

Bean :

        public void addRowListener(ActionEvent event){

           addInventoryRow = true;

        }

        public void testMethod() {

           System.out.println("hi");

        }

both action and actionListener are not invoking bean methods. how to resolve this issue? any help would be appreciated.
