Have B tell A something then and let A deal with it how it wants and return the ajax call with some javascript update to the DOM.

The children scheme doesn't matter as much with ajax calls unless you're keeping state in case the user reloads the page or something.

>                 callback: [:r | (r element id: 'C') hide])
