turning the top menu into pop-up menu

[Nitned]

Hi, I turned Topmenu into a Suspended Menu, and left only 1 button to test, I would like to know how to make this button execute another script.
example;
clicking this button will launch Client_Options, opening the Options window.

Lua code:

function init()
  menuWindow = g_ui.displayUI('menu.otui')
  menuWindow:hide()
  menuButton = modules.client_topmenu.addLeftButton('menuButton', tr('Menu'), '/images/topbuttons/menu', onoff, true)
  g_keyboard.bindKeyDown('Ctrl+Z', toggle)
  menuWindow:disableResize()
  local mw = g_ui.createWidget('Panel')
  mw:setParent(modules.game_interface.getRootPanel())
end

function terminate()
  menuWindow:hide()
end


function onoff()
  if menuWindow:isVisible() then
    menuWindow:hide()
  else
  menuWindow:show()
  end
end

Otui code:

Panel
  id: menuWindow
  !text: tr("")
  font: terminus-14px-bold
  text-align: center, top
  color: black
  anchors.left: parent.left
  anchors.top: parent.top
  anchors.right: parent.left
  anchors.bottom: parent.top
  margin-left: 32
  margin-top: 0
  margin-right: -190
  margin-bottom: -240
  width: 190
  height: 240
  @onEnter: mods.client_menu.hide()
  @onEscape: mods.client_menu.hide()

  Button
    id: optionsButton
    size: 190 40
    anchors.left: parent.left
    anchors.top: parent.top
    icon: /images/game/menu/botaoBranco
    $hover !disabled:
      icon: /images/game/menu/botaoLaranja

in .otui file under the button's declaration add:

@onClick: modules.client_options

or something similar.

Button
    id: optionsButton
    size: 190 40
    anchors.left: parent.left
    anchors.top: parent.top
    icon: /images/game/menu/botaoBranco
    $hover !disabled:
      icon: /images/game/menu/botaoLaranja
    @onClick: modules.client_options
