currently only modal inner content/view is r(e)loaded causing uncessary html/js generated like:

no modal content should be generated before displayed (when inner content/view is loaded via API) and once AJAX for (re)load is fired, whole content should be rendered/downloaded

this will improve performance when main page has a lot of modal executors and also allow greater executor buttons customizations per (re)loaded content/records

filter popup generates a lot code as well, maybe move it to AJAX completely as well
