I recently replaced Aloha editor with HalloJS in my CMS for several reasons, the most important of which are HalloJS being more leightweight and a lot easier to customize. A severe problem I have however run into is that it doesn't seem possible to init the HalloJS toolbar to elements that are dynamically added to the DOM after initial initialization of Hallo.
Judging from the source, something is definitlety happening, since a div#hallojstoolbar appears upon clicking the newly created editable in the DOM, but it isn't visible and its widgets, controls & dialogs aren't to be found anywhere.
