How does this Jasmine unit test mock call work?

Question

What is the difference between these two:

First version:

  it('Expect foo', function() {
    var response = [{'fizz': 'buzz'}];
    var jsonString = JSON.stringify(response);
    spyOn($, 'ajax').and.callFake(function(e) {
      e.success(jsonString);
    });
    expect($('#data-table tr:eq(1) td:eq(0)').text()).toEqual('buzz');
  });

Second version:

  it('Expect bar', function() {
    var response = [{'fizz': 'buzz'}];
    var jsonString = JSON.stringify(response);
    spyOn($, 'ajax');
    createAjaxCall("foo/bar/url");
    $.ajax.calls.mostRecent().args[0].success(JSON.stringify(response));
    expect($('#data-table tr:eq(1) td:eq(0)').text()).toEqual('buzz');
  });

The above two test functions are supposed to test whether an ajax call also ends up updating the HTML element with id #data-table with text 'buzz' for 1st row and 0th data element in the table. The first one is causing my Jasmine maven plugin tests to fail with weird errors that are hard to debug because it causes Jasmine maven plugin to sometimes succeed and sometimes fail. The second one doesn't seem to be failing.

I am not familiar with how the second call works. It seems to be calling createAjaxCall(), which doesn't actually call the method, but then the mock call using $.ajax.calls... is the one that actually calls it. What exactly is happening there?

Here is the error (I am using Jasmine Maven plugin version 2.2). It expected token }, but I checked and that doesn't seem to be the case, there weren't any missing }:
