Updating the GuiTextEditCtrl text field

Why doesnt the value of a GuiTextEditCtrl.text update in real time? If i enter text into the GuiTextEditCtrl it doesnt update its "Text" field.. Why is this and how can i change it?

It should be just %storedVariable = TextEditName.text; but that only works if you manually set the text field in the GUI editor. Do I need to put texteditname.setValue("Input here")? But how can i grab the "Input here" if the text field isnt updated automatically??
