Send Welcome / Double Opt-in doesn't work

[Dane Thomas]

This doesn't really have anything to do with thus plugin directly but using the jsonp interface has anyone been able to get the double_optin or send_welcome options to work?

I can get a subscription to be added fine but it doesn't honor a double_optin: false.

@danethomas if you are hitting lists that are backed by mailchimp forms, they will always be double opt-in. Single opt-in is only available via your own forms or 3rd party like wufoo.

Please let me know, can double option work with jquery ajax? I tried but it does not give any result.
Actually I want to add user without confirmation using Jquery and Ajax except PHP code.
