Automatically saving dirty objects to server

[lucasjans]

What's the best way to detect when an esEntity is dirty and automatically saving it to the server?

I've created a simple extension to monitor and changes and update them call save.

        ko.extenders.save = function (target, option) {
            debugger;
            target.subscribe(function (newValue) {
                console.log(option + ": " + newValue);
                option.save();
            });
            return target;
        };

And I can extend any object that is a column. Here's an example to save when the name is changed

this.Name = ko.observable().extend({save: this});

But what I would really like to do is extend the "isDirty." Problem is, by the time it exists, it's already returned to the viewModel. I would rather not have to dynamically for-each through the viewModel after the data is applied to extend it. Is there a better way?

When I look in here:

es.objects.RevCoCompanies.prototype.customize(function () {
\\etc...
});

isDirty still doesn't exist.

Our standard save method calls GetDirtyGraph() so only dirty entities are sent to the server during a call to Save.

Look at line 346 in this file (ignore the comment on line 345 I need to remove that as it is not slow) https://github.com/EntitySpaces/entityspaces.js/blob/master/Src/BaseClasses/EsEntityCollection.js

So how do I get notified of a dirty element on the graph? I can extend fields, but I can't extend isDirty.
