The "fixed" version would be something like this:

onClick: ((html jQuery ajax callback: ["..."]) onComplete: (
                 (html jQuery id: idOfRootCompForRedraw)
                   load html: [:h | h render: rootComponentForRedraw]))

Another alternative is to execute the callback within a script
response, saving one extra HTTP roundtrip for the "onComplete".

onClick: (html jQuery ajax script: [:s |
                "your callback actions".
                (html jQuery id: idOfRootCompForRedraw) html: [:h | h
render: rootComponentForRedraw]
               ])

I managed to get a similar behavior using Bootstrap's Popover plugin
<https://getbootstrap.com/docs/3.3/javascript/#popovers>, where the
popover is dynamically attached and its content is loaded from the
server once opened (so you get an "updated" content every time you
open it).

Submit buttons cause a full page reload, unless you handle the submit
event and return false at the end.
Why I do these days is submit almost everything using
#serializeChildren: on the form, triggered by a button or anchor that
IS NOT a submit button.

There are a lot of "recipes" like this that we should share in the
Seaside wiki or somewhere.
