`this.model = function()…` does not return any values. This is correct (you can notice lack of `return` statement). But what is your question? — Alexei Levenkov, Aug 22 '19 at 23:20

Calling document.write() just writes the value into the web page, it doesn't return anything. You need a return statement.

this.model = function() {
    return '<h1>tata</h1>';
};

Also, see Why is document.write considered a "bad practice"?
