Python Tkinter bind

Question

Возникли проблемы при передаче функции связывания в другую функцию. Несколько экземпляров Combobox. На выборах. Изменить запись. Combobox не передает функцию в требуемую функцию.

class Application(tk.Frame):

    def __init__(self, *args, **kwargs):
        tk.Frame.__init__(self)
        self.ChkOut01
        self.UpdateDia
        self.UpdateDia01

    def ChkOut01(self):
        ent_dia_d01 = ttk.Combobox(root, width=10, justify=tk.CENTER)
        ent_dia_d01 ['values'] = (" 0.38 - 0.885"," 0.50 - 1.165", \
                                  " 0.75 - 1.405"," 1.00 - 1.780", \
                                  " 1.25 - 2.270"," 1.50 - 2.525", \
                                  " 2.00 - 3.040")
        ent_dia_d01.bind('<<ComboboxSelected>>', self.UpdateDia01)

    def UpdateDia(self):
        ent_dia_d = 'ent_dia_d' + self.n
        if globals()[ent_dia_d].get() == " 0.38 - 0.885":
            globals()[ent_dia_d].delete(0, 'end')
            globals()[ent_dia_d].insert(0, ("0.885"))

    @staticmethod
    def UpdateDia01(self):
        self.n = 01
        self.UpdateDia()
        return self.n
