PhantomJS page.evaluateAsync is ignored with ajax call inside

I am trying to make an ajax call with phantomjs.

The only resource i found regarding this is: http://phantomjs.org/api/webpage/method/evaluate-async.html

Although when i try to make an ajax call though evaluateasync, the code within is not being executed. Even console.log('Async'); not being printed.

Any ideas?

var webPage = require('webpage');
var page = webPage.create();
page.open("", function(status) {
    page.includeJs("https://code.jquery.com/jquery-3.1.1.min.js", function() {
        console.log('includejs');

        page.evaluateAsync(function() {
            console.log('Async');


            $.ajax({
                url : "some url",
                type : 'post',
                success : function(data) {
                    console.log(data);
                    console.log('success');

                },
                error : function(jqXHR, exception) {
                    console.log(jqXHR+'-'+exception);
                    console.log('error');

                }
            });

        });
});});

page.evaluateAsync is not ignored, it's just that console.log inside of page.evaluate/evaluateAsync() function is not the same as in the PhantomJS script, it's running in the sandboxed environment and uou have to subscribe to it:

page.onConsoleMessage = function(msg) {
    console.log(msg);
};

Also, if you try to log an object, as in 

console.log(jqXHR+'-'+exception);

you'll get [object Object] result, instead try

console.log(JSON.stringify(jqXHR)+'-'+exception);

Even more important: if after opening one site you're gonna do ajax requests to another, run your script with --web-security=false switch to allow cross-domain XHR.

phantomjs --web-security=false evalasync.js
