Hi Issam,
Thanks for contacting Syncfusion support.
Query: Need a sample with Knockout, two way binding.
As per your request we have prepared a sample and it can be shown in the below link.
Refer the help documentation.
Regards,
Thavasianand S.
For what it is worth, when you launch that sample in the JS Playground (http://jsplayground.syncfusion.com/Sync_vapaxarw) it does not work (using Chrome).

I repaired them in my playground reference.
