[ios] "Choose My Own Password" not calling onChange

🐛 Bug Report

When you have an input with secureTextEntry the iOS Strong Password dialog pops up and it changes the text to the generated password. This works as expected and onChange is called, but when you press Choose My Own Password (picture below), it doesn’t call onChange.

I saw #21261 was closed because it didn’t follow the format, and I couldn’t find another issue created for this

To Reproduce

1. Have a <TextInput /> with secureTextEntry on iOS 12+
   • It is also helpful to have console.log on onChange and onChangeText to see what is called
2. Tap it, this should bring up the Strong Password popup
3. Press Choose My Own Password
4. The text changes visually, but it does not call onChange or onChangeText

Expected Behavior

Pressing Choose My Own Password calls onChange and onChangeText with an empty string. That way we know that the user is no longer using the secure password.

Code Example

Cannot be run on the simulator, must be run from an iPhone iOS 12+ with Autofill Passwords turned on in the Settings.

I feel this issue should be bumped up in priority.

Promoting the use of security-minded features is awesome but not calling the onChangeText with "" as the value when the user explicitly opts out of using iOS’s password generation feature can result is major issues with application internal state.

If my Input field is updating component state when onChangeText is fired, I would expect this event to fire when the user opts out of the iOS secure password feature because the Input field goes from yellow with auto-generated password filled back to it’s original styles with no text in the input.

Please reconsider the priority of this and respect Apple’s implementation of auto-gen password! I have no way to clear out auto-generated password from component state even after the user explicitly opted out of using an auto-generated password.
