Blur event gets fired in textfield, when keyboard gets hidden

I have a Titanium.UI.TextField, which has a blur event listening on it.

If I enter the textfield, I'm getting the keyboard (makes sense)

If I click on "Done" (or what ever to hide the keyboard on iOS, Titanium.UI.TextField.returnKeyType) I get the blur event. Which makes also sense.

But now, I don't want to lose the focus, I just want to hide the keyboard, if the returnKeyType gets clicked. How do I achieve this?

thanks for the information
