Ionic 4: physical back button not rerender the page

Hello Ionicers

I have an issue with my application.
When i click native back button after an action on another page that affects on previous page data, i got all correct (updated) data on the page i enter after back-action, but the page view is not changing until i click/tap somewhere.
With no such issue and everything works in the right way. The instructions for this 2 actions are the same (one code)

Any suggestions?

Can you please show me code sample.
also please try to call the data in ionViewWillEnter()
