Pagination available in widget preview mode but not available on UI page

[Sreekarr Yallap]

Hello,

I created a widget with a pagination feature. While the pagination is visible in the widget preview mode, it doesn't appear when I open the UI page directly. 

Any assistance with this would be greatly appreciated.
Thank you.
