Using deferred objects with private dynamic calling functions (Revealing pattern)

Question

I'm trying to use jQuery deferred with private dynamic calling functions like this:

var module = (function(){
    var privateFuncs = {
        privateMethod: function(val) {
            console.log(val);
        }
    };

    var success = function() {
        console.log('Success');
    };

    var publicMethod = function() {
        var functionString = "privateMethod";
        privateFuncs[functionString]('test').done(function(){
           success();
        });
    };

    return {
        init: publicMethod
    };
})();

module.init();

And I'm getting this error:

privateFuncs[functionString](...) is undefined

Is there any chance to achieve what I'm looking for?

Without the use of deferred objects, the code works like a charm, as you can see here:

JavaScript, call private function as a string inside public method without using eval (Revealing pattern)

Thanks!

EDIT:

Here's my new code:

var module = (function(){
    var privateFuncs = {
        privateMethod: function(val) {
            console.log(val);
        }
    };

    var success = function() {
        console.log('Success');
    };

    var publicMethod = function() {
        var functionString = "privateMethod";
        var deferred = $.Deferred(privateFuncs[functionString]('test'));
        deferred.done(function(){
           success();
        });
    };

    return {
        init: publicMethod
    };
})();

module.init();

The problem is that nothing happens when I create the deferred object, look at here:

This is not the correct use of jQuery.Deferred:

var module = (function(){
    var privateFuncs = {
        privateMethod: function(val) {
            console.log(val);
        }
    };

    var success = function() {
        console.log('Success');
    };

    var publicMethod = function() {
        var functionString = "privateMethod";
        var deferred = $.Deferred(function(defer) {
            privateFuncs[functionString]('test');
            defer.resolve()
        });
        deferred.done(function(){
           success();
        });
    };

    return {
        init: publicMethod
    };
})();

module.init();
