completely clean an input control

Hi,

I need to completely clean values typed in input controls (i.e.: no trace of the values should remain).

Using AW.UI.Input, I see that there is an attribute named "aw-value" that store the value inserted by the user even if I have cleaned it using the setControlText("") method. I can clean this attribute using the following line:

AW.all.myInput.getContent("box/text").element().setAttribute("aw-value","")

My question is:
there are other places (i.e. properties or attributes of the control) where the old inserted values are stored? Is there a better way to really clean the content of an input control?

thank you
