Do you observe this behavior in Android or in iOS or in both platforms?
I am asking this, because I have recently changed this behavior in Android, i.e. the text property is updated only after the EditText (this is what represents our TextField in Android) widget loses focus. Which turned out to be a bad idea, since the widget you tap on might not be focusable in touch mode, which may cause the EditText widget to never lose focus. This seems like your case.
Anyway, I am currently developing a new property which will let the user specify the behavior he wants. It will be called updateTextTrigger and will be an enum with two possible values -- FocusLost and TextChanged. The default value will be TextChanged which will be update the TextField.text property on every single character that the end user types.
This change will come with the next version we release. Please, let me know if the problem persists.
