Data kinking provides us a way, to link our data/objects to UI controls. Means, if the controls get updated, the underlying data object would also be updated. In the same way, if the data objects get updated, the controls on UI will also get updated (In case of two way linking). Means once you linked your data with the controls, you don’t need think about the data object. The syncing between data object and your UI will be taken care by the jQuery plug in.
