我用逗号分隔章节中的脚注，我希望逗号保留在章节中，但不出现在目录中。我该怎么办？
\documentclass[a4paper,12pt,oneside]{book}
\usepackage[symbol,stable,perpage]{footmisc}
\usepackage{tocbibind}
\usepackage{titlesec}
\usepackage[english]{babel}
\usepackage{pdfpages}
\usepackage{stmaryrd}
\usepackage{fancyhdr} % header and footer
\usepackage{titlesec} % adjust the layout of chapters
\titleformat{\chapter}[hang]
{\normalfont\Large\bfseries}{\thechapter}{1cm}{}
\titlespacing*{\chapter}{0cm}{*1}{*2}
%% END USER DEFINED PART
%%%%%%%%%%%%%%%%
\begin{document}
\tableofcontents
\chapter{blublublu \footnotemark $^,$ \hspace{-0.35cm} \footnotemark}
\addtocounter{footnote}{-1}
\footnotetext{bla}
\stepcounter{footnote}\footnotetext{bli}
\end{document}
先感谢您
