Solve the following python programming problem given the following code:
def _wx_initialize_view_control(self, view) : 
    ' Initializes the toolkit-specific control for a view.

        This is used to hook events managed by the framework.

        ' 
    def on_set_focus(event) : 
        ' Called when the control gets the focus. ' 
        view.has_focus = True 
        event.Skip () 
        return 
def on_kill_focus(event) : 
        ' Called when the control gets the focus. ' 
        view.has_focus = False 
        event.Skip () 
        return 
self._wx_add_focus_listeners (view.control, on_set_focus, self) 
    return 

    
    

    Fix the buggy line: self._wx_add_focus_listeners (view.control, on_set_focus, self)
