WinJS oniteminvoked stop event

Hi I have the following code

 <win-list-view item-data-source="notificationsList"
                               ng-stop-propagation
                               oniteminvoked="selectAnnouncement($event)"
                               selection-mode="'none'"
                               ng-show="notificationsList.length > 0"
                               ng-cloak>
                    <win-item-template>
                        <sp-announcement-item announcement="item.data"
                                              is-load-more-item="item.data.id === showLoadMoreAnnouncementId"
                                              is-active="item.data.id === selectedAnnouncementId"
                                              load-more-action="loadMore"
                                              is-channel-in-database="isChannelInDatabase(item.data.channelId)">
                        </sp-announcement-item>
                    </win-item-template>
                    <win-list-layout></win-list-layout>
                </win-list-view>
