Because my alert (), does not get to run ?, it will be that there is error on onadyadystatechange

This has the functionality to give click to call this function goLostpass; but it does not show me the message ie it does not go into onreadystatechange. The alert is to look for the error

function goLostpass() {
      // window.alert('Se presiono ENTER');
      var connect, form, response, result, email;

      email = __('email_lostpass').value;

      if (email != '') {
          form = 'email=' + email;
          connect = window.XMLHttpRequest ? new XMLHttpRequest() : new ActiveXObject('Microsoft.XMLHTTP');

          connect.onreadystatechange = function(){
            alert("Estoy aqui");
            if (connect.readyState == 4 && connect.status == 200) {
              if (connect.responseText == 1) {
                result = '1==1';

                __('_AJAX_LOSTPASS_').innerHTML = result;
                location.reload();
              }else{
                result = '1=x1';
                __('_AJAX_LOSTPASS_').innerHTML = result;
              }
            }else if (connect.readyState != 4){
                result = '1==2';

              __('_AJAX_LOSTPASS_').innerHTML = result;

            }

          connect.open('POST','ajax.php?mode=lostpass',true);
          connect.setRequestHeader('Content-Type','application/x-www-form-urlencoded');
          connect.send(form);
        }

      }else {
        result = '1==3';

        __('_AJAX_LOSTPASS_').innerHTML = result;
      }
    }
