We are not processing change bars in FrameMakers. The first thing we do when we communicate is to create a *.wif file from your FrameMaker files for ePublisher Pro to process this *.wif file. Wif file is almost an exact copy of your FrameMaker documents. Even in this created *.wif file change bars are ignored. At this time there is nothing you can do to get your change bars in the created html.
