PrimeFaces DataTable with custom LazyDataModel does not work with commandButton inside columns

Question

I have a datatable with a LazyDataModel that works fine with paging. However I put buttons in a column and they do not fire. If I remove the lazy mode these buttons work fine. The truth is I tried everything and just removing the lazy mode works.

        <p:dataTable 
            id="basicDT" 
            var="user" 
            lazy="true"
            value="#{userMB.userLazyDataModel}" 
            selectionMode="single"
            rowKey="#{user.id}" 
            selection="#{userMB.selectedUser}" 
            rows="10"
            paginatorPosition="bottom" 
            paginator="true" 
            paginatorAlwaysVisible="true" 
            paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
            currentPageReportTemplate="{currentPage}:{totalPages} / ({totalRecords})"
            >


            <f:facet name="header">#{msgs['userList.title']}</f:facet>

             <p:ajax  event="rowDblselect" listener="#{userMB.onRowSelect}" />
            <p:column selectionMode="multiple" style="width:36px;text-align:center"/>
            <p:column width="35">
