When the Verj.io Runtime Enviroment receives a submit from the browser, it updates 
Fields with any corresponding data and then triggers the appropriate event, executing any associated scripts.
Changes made to any of the 
Pages's Controls during this process are automatically detected and are sent back to the browser, which dynamically updates the relevant parts of the Page. This ensures a much smoother experience for end-users than would otherwise be possible.
It is also possible to manually request that a Control be refreshed during an event using the controls interface of the Verj.io JavaScript API, for example, controls.mycontrol.refresh().
