The reason this is not working is because you are explicitly ignoring
the first (what would be the cursor) argument to your component, so
neither transact!/update! (which works on your cursor, not local
component state) or set-state!/update-state! (which is applied to local
component state--what you retrieve with get-state) will work.
On a more conceptual level I would recommend keeping application
data--which stuff like "domain" and "customer-info" most certainly
are--in your cursor (a.k.a. "app data" a.k.a. the first arg to
component) vs. in your state. This will solve a number of your problems.
