Wouldn't it be more straightforward with Promise based implementation?

+    function dummyChanged()
+    {
+        var cbList = callbacks.slice();
+        callbacks.length = 0;
+        cbList.forEach(function(callback) { callback(); });

+        if (!callbacks.length)
+            dummy.foo++;
+        callbacks.push(callback);
+    };
+})();
