It is possible to use single text view widget, but you have to reparent
it on every notebook page change -- and this is not correct way.
The right solution is to create new text view for every file. So,
your code should look like this:

    def __init__(self):
        self.editors = []       # holds all textview widgets
        ...

    def new_file(self,widget):
        self.doc_num += 1
        b = len(self.documents)

        editor = gtk.TextView()
        self.editors.append(editor)
        self.tab_panel.append_page(editor, gtk.Label("ASD"))
