Ionic navPop with reload page

I want to reload the page when click on back button.
Nothing on docs how to disable page cache or reload page view

I would consider that the framework’s area of responsibility, and not something app developers should concern themselves with.

“Reload” as a concept does not (and should not) exist. You can define a function that refreshes all the data that your page is bound to, that is like a refresh.

If you want to change what the back button does, you can do that. Just search for it here in the forum.
