How to trigger ion-infinite-scroll programmatically

I have a list with ion-infinite-scroll, laso i have a loadMore() that load data from server, user can perform search request via input, so i clear the list and perfom request, but in this case spiner doesn’t show up, Is there any way to trigger ion-infinite-scroll or show spinner programmatically?

use ion-spinner directive for that --> add a flag to the spinner to only show it only when you perform your special actions.
