Displaying a var using AngularJS/HTML on the screen

Question

I'm using MEAN Stack to construct my web application. (Mongo, Express, Angular, NodeJS) I have a server.js file, html file and a css file. My server.js generates a var number which I want to get rendered on the frontend, however I'm having some trouble doing that. Let me explain, on my html there a button I created, whenever the user clicks on that button, I want this specific var to be shown the screen, but it doesn't work.

Here is the code for the creation of the button: Some Text

Below is the angularjs code for where I use the exact rendering to be occurred:

My server.js code:(Please note I'm using jsdom module)

var jsdom = require("jsdom");

  jsdom.env(
          url,
          ["http://code.jquery.com/jquery.js"],
          function (err, window) {
          // console.log("there have been", window.$("a").length, "io.js releases!");
          // alert("there have been", window.$("a").length, "io.js releases!");
          console.log(window.$("a").length);
          amountLinks = window.$("a").length;
          json.amountLinks = amountLinks;
          data = amountLinks;
  });

Does anyone know how I can fix this?

The code can be fixed as follow:

  jsdom.env(
          url,
          ["http://code.jquery.com/jquery.js"],
          function (err, window) {
          // console.log("there have been", window.$("a").length, "io.js releases!");
          // alert("there have been", window.$("a").length, "io.js releases!");
          console.log(window.$("a").length);
          amountLinks = window.$("a").length;
          json.amountLinks = amountLinks;
          data = amountLinks;
          res.send(JSON.stringify(json, null, 4))
  });
}
