CommandLink not working with Lazy Loaded Primefaces Datascroller

I am having a problem with lazy loading the Primfaces Datascroller component .

I have a jsf page that should display 10 events when the page loads. If the user wants to see more, he / she can press the button more to load and display the next 10 events. Each event line has a link that can be used to display information about the event.

    <h:form id="mainForm" >
        <p:dataScroller value="#{backing.lazyModel}" var="event" lazy="true" chunkSize="10" rowIndexVar="index">
            #{event.name}
            <p:commandLink class="view-trigger"
                value="View Event Details"
                actionListener="#{backing.initViewEventDetails(index, event)}"/>
            <f:facet name="loader">
                <p:outputPanel 
                        visible="#{backing.lazyModel.rowCount gt 10}"
                        rendered="#{backing.lazyModel.rowCount gt 10}">
                    <p:commandLink value="More" />
                </p:outputPanel>
            </f:facet>
        </p:dataScroller>
    </h:form>

The original search works fine, that is, when I click on the link for information about the event, my bean feedback is called, and I see that the index and the received events correspond to the line that I clicked on.
