Hangs during afterChange on getDataAtCell

Getting help Questions

During afterChange it hangs on getDataAtCell. If I remove the line and return then it works. I am trying to capture the actual id to do a database update. The id is in col 1

afterChange: function (change, source) {
var data;
data = change[0];

    var row = change[0][0];
    var col = change[0][1];
    var oldVal = change[0][2];
    var newVal = change[0][3];
    

    var hiddenID = hot.getDataAtCell(row, 1);

  alert(hiddenID);

return;

            $.ajax({
              url: "save.php",
              type: "POST",
              datatype: "json",
              data: {changes: change}, // contains changed cells' data

success:function(data){
$console.text(data);
},
error: function(xhr, status, error) {
var err = eval("(" + xhr.responseText + “)”);
$console.text(err.Message);
}
});
}
});

Figured it out after hot instance created add hook

hot.addHook(‘afterChange’, function(change, source) {
if(source !== ‘loadData’){
var data;
data = change[0];

    var row = change[0][0];
    var col = change[0][1];
    var oldVal = change[0][2];
    var newVal = change[0][3];

var hiddenId = hot.getDataAtCell(row,0);

change[0][0] = hiddenId;

            $.ajax({
              url: "save.php",
              type: "POST",
              datatype: "json",
              data: {changes: change}, // contains changed cells' data

success:function(data){
$console.text(data);
},
error: function(xhr, status, error) {
var err = eval("(" + xhr.responseText + “)”);
$console.text(err.Message);
}
});
}
});
