python : bind function to button - python-3.x

Question

this is my python code GUI generated from PAGE 4.6.
I want to create a function which will change the textbox value in real time example
tbCapturedImage.set("test 1").
take a look at
self.btnCapture.bind('<Button-1>', self.Capture_a)
but it cant seems to change the value of the textbox.
self.tbCapturedImage = Text(self.TLabelframe1)
self.tbCapturedImage.place(relx=0.04, rely=0.65, relheight=0.33
, relwidth=0.93)
self.tbCapturedImage.configure(background="white")
self.tbCapturedImage.configure(font="TkTextFont")
self.tbCapturedImage.configure(selectbackground="#c4c4c4")
self.tbCapturedImage.configure(width=206)
self.tbCapturedImage.configure(wrap=WORD)
self.btnCapture = Button(master)
self.btnCapture.place(relx=0.01, rely=0.92, height=45, width=982)
self.btnCapture.configure(activebackground="#d9d9d9")
self.btnCapture.configure(disabledforeground="#a7a4a7")
self.btnCapture.configure(font=font11)
self.btnCapture.configure(text='''Capture Image''')
self.btnCapture.bind('<Button-1>', self.Capture_a)
self.Labelframe1 = LabelFrame(master)
self.Labelframe1.place(relx=0.25, rely=0.48, relheight=0.43
, relwidth=0.74)
self.Labelframe1.configure(relief=GROOVE)
self.Labelframe1.configure(text='''Color Detection''')
self.Labelframe1.configure(width=740)
self.Labelframe2 = LabelFrame(master)
self.Labelframe2.place(relx=0.25, rely=0.05, relheight=0.43
, relwidth=0.35)
self.Labelframe2.configure(relief=GROOVE)
self.Labelframe2.configure(text='''Perspective Transformation''')
self.Labelframe2.configure(width=350)
self.Labelframe3 = LabelFrame(master)
self.Labelframe3.place(relx=0.61, rely=0.05, relheight=0.43
, relwidth=0.38)
self.Labelframe3.configure(relief=GROOVE)
self.Labelframe3.configure(text='''Haar-Like Detection''')
self.Labelframe3.configure(width=380)
def Capture():
tbCapture.Set("test")
def Capture_a(self,event):
self.Capture()
if __name__ == '__main__':
vp_start_gui()

You have to use self and set instead of Set
And probably you should use tbCapturedImage instead of tbCapture
def Capture(self): # self
self.tbCapturedImage.set("test") # self, set and tbCapturedImage
BTW: you can use command= in Button instead of bind
self.btnCapture = Button(master, command=self.Capture)
or
self.btnCapture.configure(command=self.Capture)
command= doesn't send event so method doesn't need argument event
