Needs a caret

The cursor position is not accounted, nor displayed (the "input-focused" class is removed from the input even when inputReadOnly is set to false), for this widget e.g. 
"12|34"
then press delete on the keypad should result in
"1|34" rather than "123"

In the iOS version the user cannot tell which input is active. In Android it's more clear but still needs a caret for more user feedback.
