Well, just trying things a bit, this seems to work:

     html div
         onClick: (html jQuery ajax
             callback: [ :val |
                 val inspect.
                 self requestContext respond: [ :response |
                         contentType: 'text/json' seasideMimeType;
                         nextPutAll: {'what arrived was'. val} asJson
             value: (JSStream on: 'this.innerHTML')
         with: 't2'.
