Keyboard over popup on iOS

I have a textarea in a popup. When focus on it, the keyboard covers part of the popup so the user can’t fill the textarea.

Here is an image of the problem on iOS:

An this is how it looks on Android:

For iOS I’m using

cordova.plugins.Keyboard.disableScroll(true);

I’m having the same issue. Is there any simple way to reposition the popup or to only make the popup scroll (making the rest of the app static) ?
