why this not working on matrix

self.addControl(self.img)

self.chk = [0]*9
self.chkbutton = [0]*9
self.chkstate = [False]*9
for obj in self.chk:
            self.addControl(obj)
            obj.setVisible(False)
        for obj in self.chkbutton:
            self.addControl(obj)

        self.cancelbutton = xbmcgui.ControlButton(250 + 260 - 70, 620, 140, 50, 'Cancel', alignment = 2)
        self.okbutton = xbmcgui.ControlButton(250 + 520 - 50, 620, 100, 50, 'OK', alignment = 2)

        self.addControl(self.okbutton)
        self.addControl(self.cancelbutton)

def onControl(self, control):
        if control == self.okbutton:
            if self.anythingChecked():
                self.close()
        elif control == self.cancelbutton:
            self.cancelled = True
            self.close()
        try:
            if 'xbmcgui.ControlButton' in repr(type(control)):
                index = control.getLabel()
                if index.isnumeric():
                    self.chkstate[int(index)-1] = not self.chkstate[int(index)-1]
                    self.chk[int(index)-1].setVisible(self.chkstate[int(index)-1])

        except: pass

on versions like v18, v17 works pretty well but on matrix neither "OK" , neither "Cancel" works
