Accel not working in gedit 3 plugin

Question

I tried to write a small plugin for Gedit 3 that uses GObject introspection. The corresponding piece of code, shown below, is only aimed at creating an environment where I could then fit into the callback function for the button. However, the button accelerator does not work.

• What is wrong with this code?

• I am using the tutorial here and the python documentation for GTK 3. Are there any other links you know about?

  from gi.repository import Gtk, Gedit, GObject 
  ui_string = """<ui>
  <toolbar name="ToolBar">
  <separator />
  <toolitem name="Test" action="Test" />
  </toolbar>
  </ui>
  """
  class test:
      def __init__(self, plugin, window):
          self.window = window
          self.plugin = plugin
          self.ui_id = None
          manager = self.window.get_ui_manager()
          action_group = Gtk.ActionGroup("TestPluginactions")
          action_test_button = Gtk.Action(name="Test",
              label="Test",
              tooltip="Test",
              stock_id=Gtk.STOCK_EXECUTE)
  
          action_test_button.connect("activate", self.testcallback)
          action_group.add_action_with_accel(action_test_button, "<Ctrl>l")
  
          manager.insert_action_group(action_group, -1)
          self.ui_id = manager.add_ui_from_string(ui_string)
          manager.ensure_update()
  
      def deactivate(self):
          manager = self.window.get_ui_manager()
          manager.remove_ui(self.ui_id)
          self.ui_id = None
          self.window = None
          self.plugin = None
  
      def testcallback(self,unused):
          dialog1 = Gtk.MessageDialog(self.window,Gtk.DialogFlags.DESTROY_WITH_PARENT,
              Gtk.MessageType.ERROR,Gtk.ButtonsType.OK,"TEST")
          dialog1.run()
          dialog1.destroy()
  
  
  class WindowActivatable(GObject.Object, Gedit.WindowActivatable):
      window = GObject.property(type=Gedit.Window)
      def __init__(self):
          GObject.Object.__init__(self)
          self.instances = {}
  
      def do_activate(self):
          self.instances[self.window] = test(self, self.window)
  
      def do_deactivate(self):
          if self.window in self.instances:
              self.instances[self.window].deactivate()
