Nativescript angular 2 RadListView LoadOnDemand back to previous page not working (evaluating 'child.onLoaded')

Question

Hi Currently I am using nativescript-telerik-ui plugin in my {N} project and using RadListView like below

<RadListView #myRadListView [items]="posts"
             loadOnDemandMode="Auto" (loadMoreDataRequested)="onLoadMoreItemsRequested($event)"
             itemDeleteAnimation="Fade" [listViewLayout]="layout">
    <template tkListItemTemplate let-post="item" let-index="index">
        <!--- data goes here -->
    </template>
    <template tkListViewHeader>
      <Label text="next page" [nsRouterLink]="['/next-page']"></Label>
    </template>
</RadListView>

In NextPage component when user clicks on back button ActionItem I am redirecting page to posts page(i.e RadListView page) like below

goBack(){
        this.routerExtensions.backToPreviousPage();
    }

It working fine when 'loadOnDemandMode' not triggered i.e with initial items loaded in list. I am getting below error when list refreshes with loadOnDemandMode and clicks on next page and back from that page using backToPreviousPage()
