[Orgmode] Elisp code to insert a word in table

[ishi soichi]

Hi. I'm trying to write an elisp code to enter words into a table of org-mode.

after designating a buffer, which already contains a table, I simply wrote,

    '(insert "test!" @2$2)

does not work obviously.

Do I need to move the "point" to the particular cell before inserting?

Thanks in advance.
