Copy paste image in visual editor doesn't work - no attachment saved.

[pr-dtakac]

Hi, when I paste image in visual editor, image is broken and there is no attachment after issue save. I found the bug in javascript, where only inputs from dynamic edit field are submitted. After this change it works. Can you check it and fix it? Thanks a lot.
