Solve the following python programming problem given the following code:
def start(self, callback) : 
    '
        :type callback: Callable(check_handle: check)
        ' 
    def cb_wrapper(check_h) : 
        callback (self) 
self._ffi_cb = ffi.callback ('void (*)(uv_check_t *)', cb_wrapper) 
    libuv.uv_check_start (self.handle, cb_wrapper._ffi_cb) 

    
    

    Fix the buggy line: libuv.uv_check_start (self.handle, cb_wrapper._ffi_cb)
