Python and KivyMD: using a .json file / dict to dynamically add buttons and bind to a later defined function

Question

'''
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.button import Button
from kivy.app import App

dict = {
    "Button Name": "Create Event",
   "Button Function": 'self.create_event'},
{
   "Button Name": "Find Event",
   "Button Function": "self.find_event"},
{
     "Button Name": "Create Player",
    "Button Function": "self.create_player"},
{
     "Button Name": "Find Player",
    "Button Function": "self.find_player"
}
class DemoBox(BoxLayout):

    def __init__(self, **kwargs):
        super(DemoBox, self).__init__(**kwargs)
        self.orientation = "vertical"

        for button in dict:
            btn = Button(text=button['Button Name'])
            btn.bind(on_press=button['Button Function'])
            self.add_widget(button)

    def create_event(self):
        print("Going to the Create Event Page")

    def create_player(self):
        print("Sending to create player page")

    def find_event(self):
        print("Heading to find event page")

    def find_player(self):
        print('We are in the Find Player page')

class DemoApp(App):
    def build(self):
        return DemoBox()

if __name__ == "__main__":
    DemoApp().run()

I am getting an error stating that self.create_event() is not callable

the actual code will be saved in a .json file and contain far more buttons, and will hopefully save code editing. Just allowing future buttons to be added by adding to the .json file / dict. Then defining the function, which will change page / execute code.
