Getting response From Ajax call

Question

When trying to get the responseText from an ajax call built in plain vanilla javascript, Firebug seems to see the request but one cannot get a reference to the responseText.

This is the code for function

function getAjaxResponse(){    
    var ajaxObj = getAjaxObj();
    ajaxObj.open('get', 'responsePage.php', true);
    ajaxObj.onReadyStateChanged = function(){
        if(ajaxObj.readyState == 4
            && ajaxObj.status == 200){
                //no functions are getting fired in here                
                //this does not get logged to console
                console.log(ajaxObj.responseText);
                //neither does this
                console.log(2);
        }
    };
    ajaxObj.send(null);

   //this does gets logged to console
   console.log(1);
}

function for the ajax object

function getAjaxObj(){
    var req;  
    if(window.XMLHttpRequest){
        try{
            req = new XMLHttpRequest();                                                                 
        } catch(e){
            req = false;
        } finally {
            return req;
        }
    } else {
        if(window.ActiveXObject){
            try{
                req = new ActiveXObject("Msxml2.XMLHTTP");
            } catch(e){
                try{
                    req = new ActiveXObject("Msxml.XMLHTTP");
                } catch(e){
                    req = false;
                } finally {
                    return req;
            }
            }
        }
    }
}

OnReadyStateChanged needs to be onreadystatechange. JavaScript is case-sensitive.

ajaxObj.onReadyStateChanged: onreadystatechange should all be lower case (and without the trailing 'd')
