Can you provide a link to the page your working on? When I try to add options to the example multiSelect on the home page of the page you provided using the console I can easily add options and it works fine.

$('#aloha').multiSelect('addOption', { value: 'test', 'text': 'wohoo'});

Perhaps you can try this in your console on the element your trying to modify?
