It's working fine on UI pages when i click on try it option it works good but come to change request table it's doesn't work 
I mean additional information field doesn't validate on table level ui pages doesn't work properly

I believe it should work the same way when UI page is called from table record using UI action

[Anish9515]

 table level dialog it doesn't show any mandatory for additional information or while submit empty additional information it's submitted without validation

Client script within UI page will behave the same when it's called from UI action or directly

Did you debug by adding alert?
