            dataType: "jsonp",
            jsonp : "callback",

The ajax method can receive a success and error callback functions as part of the settings. Something like this:

   $.ajax({
        url: this.base_url + 'getPTS',
        dataType: "jsonp",
        jsonp : "callback",
        contentType: 'application/x-javascript',
        success: function(data, textStatus, jqXHR){
            console.log(data);
            // your callback function here
        },
        error: function(jqXHR, textStatus, errorThrown){
            // callback in case of error
        }
    });
