OK – I found a way to solve my problem. I put all files back to the original condition, then I copied index_bone.php and option.php from the BizSphere Theme directory and pasted into my Child-theme directory, then made the above changes. But that seems a little awkward because if the Theme gets upgraded, the files index_bone.php and option.php in my Child-theme may be obsolete.
Is there a better way to do this ?

Sorry – I had to install the header both in the Customize window and the Header window. It works now.
