Environment

• Using NativeScript Playground

Describe the bug
On Android if the keyboard type of a textfield is set to number, you can't enter a string into that field.
But on iOS, either by using the Paste menu, or by using one of the recommended text in the top row the keyboard, you can enter string into a textfield which is set to number type.

To Reproduce
https://play.nativescript.org/?template=play-ng&id=UMZOg2
Try pasting a string into the textfield in this demo app and press the button and see the logs.

Expected behavior
I expect it to not let the user type string into a number field on iOS, just like on Android.
