If i remember OP wanted completion on \[ with \] with the "\" included
thats why there is \ in insert.
This version complete the "[" with "]" and put point between the [].

,----[ insert pair of [] ]
| (defun insert-second-hook ()
|   (interactive)
|   (insert "[]")
|   (goto-char (- (point) 1)))
| (global-set-key (kbd "\[") 'insert-second-hook)
`----

when you press key [ it insert the two [] and then go back one char.
Note that is a very simple code and can be much better, look at
pair-mode.el.
Note also you can set key [ locally for a special mode with
`define-key' instead of setting it globally with `global-set-key'.

Personnaly i don't like completion on pairs so i don't use that :)
