editing an item in a jsonb column

[Adeering]

Im trying to use this to edit fields inside a jsonb column...not even sure where to start on setting up the form I have this so far:

<%= best_in_place @character, 
	:data, url: user_character_path(current_user, @character), 
	as: :input, activator: "#exp-field",
	inner_class: 'form-control' %>

But this displays as object and not sure what to put to make it reference an individual item inside the jsonb column
