KendoGrid Get modified column id - kendo-ui

Question

On my Kendo grid, I have "editable=true" and datasource with "autoSync=true". As I click on a cell, it becomes editable and when leaving the cell it executes the transport's update event.
That's all fine.
In the update event I have access to the row of the dataset model containing all the values of the modified row (although with editable=true and autosync, only one column value would have been modified).
I need to know which column / field was modified?
Ideally I thought that info would be in the arguments (options) supplied to the update event.
dataSource = new kendo.data.DataSource({
autoSync: true,
transport: {
update: function (options) {
// options does not tell me which model field was updated?
...
But since it isn't there, I suppose I need to bind to the model's set event, but I cannot get that to work.
Any ideas?

Never mind this answer! I read the question all wrong.
I think I got it working the way you like.
Is this jsFiddle what you're looking for?
var ds = new kendo.data.DataSource({
autoSync: true,
transport: {
read: function(options) {
options.success([
{ Id: 1, A: 'Hello', B: 'World' },
{ Id: 2, A: '1', B: '2' },
{ Id: 3, A: 'fdasf', B: '4523' }
]);
},
update: function (options) {
var uid = ds.data().find(function(p) {return p.Id == options.data.Id;}).uid;
var tr = $('#grid .k-grid-content tr[data-uid="'+uid+'"]');
console.log(tr);
//Do something with tr
}
},
schema: {
model: { id: "Id" }
}
});
$('#grid').kendoGrid({
dataSource: ds,
editable: true,
});
