如何在kivy上发生事件时递增计数器

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

class CounterApp(App):
    def build(self):
        layout = BoxLayout(orientation='vertical')
        self.counter = 0
        self.button = Button(text=f'Click me! Count: {self.counter}')
        
        # 绑定按钮点击事件到increment_counter方法
        self.button.bind(on_press=self.increment_counter)
        
        layout.add_widget(self.button)
        return layout

    def increment_counter(self, instance):
        self.counter += 1
        self.button.text = f'Click me! Count: {self.counter}'

if __name__ == '__main__':
    CounterApp().run()
