Viewer Side AJAX using SACK not Working… HELP!

Ok I am trying to setup some viewer side ajax for non logged in users (no registration on my site). I am trying to use SACK and I am having a bunch of trouble.

I am putting my add_action into my themes functions.php file and it looks like so.

add_action('wp_head','myplugin_js_header');
add_action('wp_ajax_nopriv_someaction','tehcallback');

function myplugin_js_header(){
	wp_print_scripts(array( 'sack' ));
}

also inside my functions.php file is my callback which looks like this

function tehcallback(){
echo "alert('1')";
die();
}

Not trying to do anything just trying to get a return at this point.

I have a java file which I add to the header which has my code that executes on click of a specific link.

function javafunc(url,postid,obj){

var mysack = new sack('https://localhost/tehsite/wp-admin/admin-ajax.php');

mysack.execute = 1;
mysack.method = 'POST';
mysack.setVar("action", "nopriv_someaction");
mysack.setVar("url", url.value);
mysack.setVar("postid", postid.value);
mysack.setVar("obj", obj.value);
//mysack.onError = function() {alert('Ajax error')};
mysack.runAJAX();

return true;
}

I have tested and by clicking the link it does reach the java part. But then nothing happens I never get any sort of response from the server. No error or anything. Does anyone know what is wrong here?
