Wrong behavior when translate Class to ES5

[Jack-Works]

TypeScript Version: 2.3.4
Code

class N {
    q() {}
}
let x = new N().q.name

Expected behavior:
x should be "q"
Actual behavior:
x is ""

Problem

var N = (function () {
    function N() {
    }
    N.prototype.q = function () { };
    //  ↑ should be N.proptotype.q = function q() {};
    return N;
}());
