EL expression for Conditional DFF on the basis of transaction type

Summary:

I want to make a DFF conditionally required on the basis of a specific movement request transaction type and for that I wrote an EL expression, which is not working.

I have tried inputting transaction type name as well as transaction type id, but it is not working.

#{bindings.TransactionTypeId.inputValue eq '300000003220829'}

#{bindings.TransactionTypeId.inputValue eq 'DD-Cancel DA'}

Can anyone of you identify what's wrong in this EL expression please.
