Solve the following python programming problem given the following code:
def apply(self, func, args = (), kwargs = { 
    
}) : 
    _level = kwargs.pop ('_level', None) 
    window = self._get_window () 
    offset = _offset (window, self.center) 
    def f(arg, window, min_periods) : 
        minp = _use_window (min_periods, window) 
        return algos.roll_generic (arg, window, minp, offset, func, args, kwargs) 
return self._apply (f, func, args = window, kwargs = kwargs, center = False) 

    
    

    Fix the buggy line: return self._apply (f, func, args = window, kwargs = kwargs, center = False)

#Here is Python code to fix the buggy line: return self.

return self._apply (f, func, args = args, kwargs = kwargs, center = False)
