Widget...Editable Text...TextBox...Volatile


I have problems with getting it work:

I have a widget with two editable Texts.
I call two different events on TextChanged.
Than i want to output it with two textBoxes.
With one editable Text i have no problems.
But with the first editable Text it works when i check the Volatile Box.
But only one time. Than i have to set the other Volatile. And once again. It works only one time.
What is the problem here? And what is this functionality?
Both editable Texts have exactly the same flow, only the events are named different.
