jquery - Javascript closures and scope issues

I can't wrap my head around javascript closures. I want 4 random numbers, but only get the the last one replicated 4 times.

Javascript

$(function() {      

  function setNewNumber(element) {
    return function (newNumber) {
      element.text(newNumber);
    }
  }


  $('.number').each(function() {
      $.get('http://www.random.org/integers/?num=1&min=1&max=6&col=1&base=10&format=plain&rnd=new', 
        setNewNumber($(this))
      );
  });

});

HTML

A working plunker example

Any hints?

Answer

The get request is being cached.

(That is to say your understanding of closures is correct and the code is working correctly).

From comments, because this is relevant:

You can request multiple numbers from random.org at the same timer per their API. Instead of using four requests, use num=' + $(".number").length and then do a little parsing
