Dynamic form and date format in angularjs and node js

I hope you can help me I have some doubts about nodejs and angularjs, I'm just starting with this,

I am doing a project in nodejs with angularjs and I found this example of a project

my question

How can I do that to open another form within a same page as it does in the demo of the link? I hope you can explain me and my question is now about the format of the time, I am trying to get the date and now of this moment and for that use the following

Var datetime = require ('node-datetime');

Var date = Date.now ();
Var datenow = new Date (date);
Var date = datenow.toString ("dd-mm-yyyy HH: mm"). Replace (/ T /, '') .replace (/\..+/, '');

And the consula shows this as a result

But I wish it was this way

2017-05-18 12:17:59

And the other doubt how I can make more dynamic and open a form inside another as in the demo link I leave, I hope you can help me and thank you for your time
