component's add_first() method works abnormal when add a chart

[wangw37]

This works as expect when I click each button:

import justpy as jp

def button_clicked(self, msg):
    span = jp.P(text=self.text)
    self.myd.add_first(span)

def chart_test(request):
    wp = jp.WebPage()
    dbutton = jp.Div(a=wp)
    dcontent = jp.Div(a=wp)

    b = jp.Button(a=dbutton, text='bar', click=button_clicked,    classes='m-2 cursor-pointer inline-block rounded text-white bg-blue-500 py-1 px-3')
    b.myd = dcontent
    b = jp.Button(a=dbutton, text='column', click=button_clicked, classes='m-2 cursor-pointer inline-block rounded text-white bg-blue-500 py-1 px-3')
    b.myd = dcontent
    b = jp.Button(a=dbutton, text='line', click=button_clicked,   classes='m-2 cursor-pointer inline-block rounded text-white bg-blue-500 py-1 px-3')
    b.myd = dcontent
    b = jp.Button(a=dbutton, text='spline', click=button_clicked, classes='m-2 cursor-pointer inline-block rounded text-white bg-blue-500 py-1 px-3')
    b.myd = dcontent

    return wp

jp.justpy(chart_test)

but if I change button_clicked like below, add chart when clicked, it is strange, it always show the duplicated chart, not follow what I clicked:

def button_clicked(self, msg):
    my_chart = jp.HighCharts(classes='m-2 p-2 border')
    my_chart.options.chart.type = self.text
    my_chart.options.title.text = self.text
    my_chart.options.xAxis.type = 'datetime'
    my_chart.options.series.append(jp.Dict())
    my_chart.options.series[-1].data =  [[1651356000000, 190506], [1651442400000, 179842], [1651528800000, 170043], [1651615200000, 174911], [1651701600000, 172817], [1651788000000, 160281], [1651874400000, 172316], [1651960800000, 169727]]

    self.myd.add_first(my_chart)

additional, directly delete_components() and add_component() or jp.HighCharts(a=xxx) not ok too at my side
