Add support for dynamically loaded editors

[Ageu-Meireles]

The current code works perfectly when all elements are previously positioned and loaded on the page, but it is eventually necessary to dynamically introduce elements through javascript code and ajax requests, an event that is not currently covered. Therefore, having an event observer that handles editor initialization dynamically is essential to maintain accurate operation in different scenarios, allowing you to create responsive and robust applications with less work.

@Ageu-Meireles @hvlads A bit late but I think it would be great if this had some documentation / a section in the README
