I have reagent/atom with a vector of maps. The atom is populated viajson/transit, websocket::onMessage using reset! each time, I create an html table with the atom. The table updates when I add to the vector but it does not work if I update a map in the vector. In fact, even when I add to the vector, the table cells only update if I refresh the page.

I have a sort of general component design question. I'm thinking about writing a color picker - how would you typically return the chosen values? The obvious answers to me seem to be either pass a cursor to the component, or you provide it with some callbacks. I've mostly gone with something like cursors before, but if I want things to "happen" (like sending data to a server), would you just go with callbacks?
