How to change wxpython gizmo LED color when button is clicked

I want to change the colour of a wx gizmos led when the wx button is clicked.

My example is as follows.

import wx
import wx.lib.gizmos.ledctrl as led

class Main(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, parent = None, title ="LED test")
        panel = wx.Panel(self)
        self.myLED = led.LEDNumberCtrl(panel, -1, pos = (150,50), size = (100,100))
        self.myLED.SetBackgroundColour("gray")
        self.myButton = wx.Button(panel, -1,  "myButton", pos =(50, 50))
        self.myButton.Bind(wx.EVT_BUTTON, self.changeLEDColor)

    def changeLEDColor(self,event):
        self.myLED.SetBackgroundColour("green")


if __name__ == "__main__":
    app = wx.App()
    frame = Main()
    frame.Show()
    app.MainLoop()

I expected the led colour to change to 'green', when I click 'mybutton', but it is still 'gray'.

What's wrong with my example?

Adding self.Refresh() or self.myLED.Refresh() will trigger the repaint. Here's the link to the docs. If it flickers, look into wx.Frame.SetDoubleBuffered(True) - docs
