Javascript - callback function

Question

This seems in my head like it should work but I cant figure out why it doesn't:

(function ($) {

$.fn.extend({

    facebook: function (opts, callbackFnk) {

        var $this = this;
        ...
        ...
        ...

        $this.fbGetFriends = function( clback ){
            jsonUrl = fbMe + '/friends?access_token=' + token + '&callback=?';
            $.getJSON( jsonUrl, function( json ){
                console.log(json.data[0].name);
                clback.call(json);
            }); 
        }
        ...
        ...
        ...

In the console log the first name appears

In my other script:

var facebook = $.fn.facebook(
    { 
        myClientId  : '###############', 
        mySecret    : '##############' 
    }
);

facebook.fbOnLogin = function(){
    user = facebook.userDetails();
    token = facebook.getToken();
    facebook.fbGetFriends(function( json ){
        for ( var i in json ) {
            console.log( 'friends: ' + i + ' ' + json[i] );
        }
    });
}

In console log im getting nothing displayed and in previous tests its displaying errors data undefined.

Can anyone tell me where im going wrong?

You don't need clback.call, just clback(json) is enough.
