Dynamic button text

[Philbot]

hi I am putting some code together that uses a pickle file that saves my data from previous session. I have a set up page that allows the users to change the text on the buttons but I am having way to much trouble trying to get the buttons to update using a textvariable and been on the google all day almost

Hope some one can point me in the right direction please.

self.MyList = loaddata()
        print(self.MyList)

        self.text1=((self.MyList[4]))
        print(self.text1)


   



        self.button1 = tk.Button(self.frame, textvariable  = self.text1, width = 25, command=self.capture_asset)
        self.button1.grid(row=2, column=3) 

Mylist comes from the pickle file when I print self.text1 is fine and shows the text string I want to put on the button but the button shows a blank text?
