$ionScrollDelegate is slow in refreshing the view

I have an Angular UI Tab in my ion-content and each time a tab is clicked the view height is changed because the number of items are changed. I have used $ionScrollDelegate to resize the scroller whenever the tab is clicked but there is a small time delay.

Any way to overcome that? Any way to directly access the scroller and call the resize right away without going through the ionScrollDelegate service?

Thanks.
