Yep. In my experience, I think the only time I found it not to send
any extra param is if the value of the param is empty (or undefined, I
believe).
In the example, if:
$("#country").val();
returns nothing.

You might want to try to test it with a hard-coded value:
extraParams: {
country: function() { return 'USA'; }
}
