It's actually a simple answer.
Your function is returning a string rather than the div node. appendChild can only append a node.
For example, if you try to appendChild the string:
var z = '<p>test satu dua tiga</p>'; // is a string
document.body.appendChild(z);
The above code will never work. What will work is:
var z = document.createElement('p'); // is a node
z.innerHTML = 'test satu dua tiga';
document.body.appendChild(z);
