Solve the following python programming problem given the following code:
def _wrap_next_tick(self, callback, cleanup) : 
    handle = { 
        'removed' : False, 
} 
    def wrapper(* args, **kwargs) : 
        was_removed = handle ['removed'] 
        if (not was_removed) : 
            self.remove_next_tick_callback (callback) 
            return callback (* args, ** kwargs) 
else : 
            return None 
wrapper.handle = cleanup 
    return wrapper 

    
    

    Fix the buggy line: wrapper.handle = cleanup
