How to update \sectiontitle and \chaptertitle with \putbib and \bibliography?

Question

• Pagestyles are defined with titlesec. A two-sided template is used, and in the main pagestyle \chaptertitle is shown in the header of even pages and \sectiontitle in the odd ones.

• natbib is used to allow for author citation (\citeauthor). In addition, the \bibsection command is provided, which I renewed to have \section*{} titles when showing partial lists and \chapter*{} when showing the global references list.

• bibunits is used to define and show partial references lists.

I want \sectiontitle and \chaptertitle to be updated with \putbib or \bibliography so that the headers show \bibname, instead of the previous section/chapter. But, since starred variants are used, I can't get it done.

I've tried renewing them by hand just before calling \putbib or \bibliography:

\renewcommand{\sectiontitle}{\bibname}
\renewcommand{\chaptertitle}{\bibname}

but I get no difference.

Do you know how to update the headers when starred chapters or sections are created?

MWE:

\documentclass[a4paper,titlepage,10pt,twoside,openright]{report}

\usepackage{etoolbox}

\usepackage[]{natbib}
\usepackage[globalcitecopy]{bibunits}
\defaultbibliography{IEEEfull,IEEEexample}
\defaultbibliographystyle{IEEEtranSN}
\renewcommand{\bibsection}{\section*{\bibname}}

\usepackage[pagestyles,explicit]{titlesec}

\newpagestyle{main}{ \headrule \footrule %head and foot rules
 \sethead[][][\chaptertitle] %head-even
 {\sectiontitle}{}{} %head-odd
 \setfoot[][\thepage][] %foot-even
 {}{\thepage}{} %foot-odd
}

\usepackage{lipsum}

\begin{document}

\pagestyle{main}
\assignpagestyle{\chapter}{main}

 \begin{bibunit}
  \chapter{Introduction}

  \lipsum[1-5] \cite{IEEEexample:article_typical}

  \section{First section}
  \cite{IEEEexample:shellCTANpage} \lipsum[1-4]

  \section{Second section}
  \lipsum[2-6] \cite{IEEEexample:IEEEwebsite} \lipsum[7-11]

  \nocite*{IEEEexample:book_typical,IEEEexample:articledualmonths}  

 \renewcommand*{\sectiontitle}{\bibname}
  \putbib
 \end{bibunit}

 \cleardoublepage
 \renewcommand{\bibsection}{\chapter*{\bibname}}
 \bibliographystyle{IEEEtranSN}
 \bibliography{IEEEfull,IEEEexample}
 \cleardoublepage

\end{document}

I would like the headers in pages 5, 7 and 8 to display \bibname. Page 6 is correct, since it is the even page of the first chapter (Introduction).

After the answer by @cfr, y tried the next change:

\renewcommand{\bibsection}{\section*{\bibname}\sectionmark{\bibname}}

instead of

\renewcommand{\bibsection}{\section*{\bibname}}

and

\renewcommand{\bibsection}{\chapter*{\bibname}\chaptermark{\bibname}}

instead of

\renewcommand{\bibsection}{\chapter*{\bibname}}

And it works!

If biblatex is used instead of natbib, it may be accomplished with:

\defbibheading{bibliography}[\bibname]{\chapter*{#1}\chaptermark{#1}}
\defbibheading{subbibliography}[\bibname]{\section*{#1}\sectionmark{#1}}

Not fully tested as I can't compile the MWE properly:

\documentclass[a4paper,titlepage,10pt,twoside,openright]{report}
\usepackage[]{natbib}
\usepackage[globalcitecopy]{bibunits}
\defaultbibliography{IEEEfull,bibfile}
\defaultbibliographystyle{IEEEtranSN}
\renewcommand{\bibsection}{\section*{\bibname}\markboth{\leftmark}{\bibname}}

\usepackage[pagestyles,explicit]{titlesec}
\usepackage{fancyhdr}
\fancypagestyle{main}{%
  \fancyhf{}
  \renewcommand{\footrulewidth}{.4pt}
  \fancyhf[reh]{\leftmark}%
  \fancyhf[loh]{\rightmark}%
  \fancyhf[cf]{\thepage}%
}

\usepackage{lipsum}

\begin{document}

\pagestyle{main}
\renewcommand{\sectionmark}[1]{\markright{#1}}
\renewcommand{\chaptermark}[1]{\markboth{#1}{}}
\assignpagestyle{\chapter}{main}

  \lipsum[2-6] \cite{rutishauser66} \lipsum[7-10]

  \nocite{brent85,cavallaro88}

 \renewcommand*{\sectiontitle}{\bibname}
  \putbib
 \end{bibunit}
