I use
$(\'#test\').unbind(\'click\');
to remove the click event on the #test item. How do I make the item clickable again?

Take a look at this question Rebind DOM Event with jQuery
Josiah's solution is preferable but if you really wanted to unbind the click event entirely I believe you could do this:
var storedClick = $('#test').data('events').click[0].handler;
$('#test').unbind('click');
$('#test').bind('click', storedClick);
Remember that data('events').click is an array so you would need to store the handler for every member of the array.
