Hmm, this is working for me (zsh-5.4.2-114-g45f3169):

% setopt histnofunctions
% revsrch() { zle history-incremental-search-backward waggle }
% zle -N revsrch
% bindkey '^R' revsrch
%
failing bck-i-search: waggle_

There are a few reasons why repeating the binding might not repeat the
search when a user-defined widget is involved.  Perhaps post your
function?
