Changing maximum number or replicas doesn't work properly on iOS

[kshmir]

I tried to set the replicas to a number bigger than 40 and it didn't work.

Checked the code and it seems that the onSubmitEditing event will not trigger. Maybe trigger it manually when blurring?

It did work indeed when I used a bluetooth keyboard hooked to my iPhone, so the code actually works, it's just the event not firing up properly.

Great app btw 😄
