Field Interactions: setValue doesn't update the character count display of the field

[Luuk93]

Hi, I am new to using the field interactions and am starting out with a simple one. Trimming trailing spaces from a name field after the field value changes.

I have the code below working however the character count that is displayed on the field doesn't update (so if it removes one trailing space from "John " then the count stays as 5/50. This isn't a major problem but it's a bit annoying and makes me think I'm doing something wrong? (have included screenshot). Is there anyway to have it update the count?

var valueTrimmed = API.getActiveValue().trim()
API.setValue(API.getActiveKey(), valueTrimmed)

Thank you!
Luke
