Mapping using tpope/vim-surround only works with command

I have this mapping to surround a Word with jQuery id selector $("#...") and it works fine using a command:

command! JqId normal viwo^[i#^[ysiW"ysiW)i$^[Ennoremap <Leader>jqid :JqId<CR>

But I cannot make it works only with the mapping, it inserts the $ sign, but the vim-surround commands do nothing:

nnoremap <silent> <Leader>jqid viwo^[i#^[ysiW"ysiW)i$^[E

I also tried this (for testing purposes) and it doesn't work either:

nnoremap <silent> <Leader>jqid ysiW"

Any hint? Thanks!
