Vim - onoremap from learnvimscriptthehardway doesnt work in my case - vim

Question

As i have read the book. I have encounter the onoremap comman, especially this one:
:onoremap in( :<c-u>normal! f(vi(<cr>. But when i pressed din<shift>9, where <shift>9 is parenthesis, to delete content of next argument in parenthesis, nothing happened - just cursor moved up one line. Same here : :onoremap il( :<c-u>normal! F)vi(<cr> where cursos Find backwards the parethesis, but did nothing more.
It is weird, and even more strange because it worked few days ago (nothing has changed). What can be the problem?
I have even used vim -u NONE <somefile>, without loading .vimrc, random file with parethesis inside, and map it once again :onoremap in( :<c-u>normal! f(vi(<cr>, but even then didnt work. I reallt dont get it.
verb omap in( :
o in( * :<C-U>normal! f(vi(<CR>
