How can I change Keyname parameter value?

when create schedule keys, keyname parameter which I can control in revit is created.
but I cannot change parameter by dynamo
Is it impossible?

  • schedule key which I create for interior finish

-In model view(floor plan), there are keynames. and It works properly.

-In dynamo, I cannot change keyname parameter. it doesn’t work. Nothing change


Everything looks good.
Can you drop dummy rvt file and dyn script?
