 - The **DataSource** does not automatically sort, group, filter, or otherwise shape pushed data. For this reason, the **DataSource** and the UI component bound to it can be out of sync. To prevent this, enable the [reshapeOnPush](/api-reference/30%20Data%20Layer/DataSource/1%20Configuration/reshapeOnPush.md '/Documentation/ApiReference/Data_Layer/DataSource/Configuration/#reshapeOnPush') property. We also recommend specifying the [pushAggregationTimeout](/api-reference/30%20Data%20Layer/DataSource/1%20Configuration/pushAggregationTimeout.md '/Documentation/ApiReference/Data_Layer/DataSource/Configuration/#pushAggregationTimeout') property to reduce the number of updates and recalculations.
 - The **push** method does not raise data source modification events (for instance, **onInserted**, **onRemoved**, **onUpdated**). Handle the [onPush](/api-reference/30%20Data%20Layer/Store/1%20Configuration/onPush.md '/Documentation/ApiReference/Data_Layer/ArrayStore/Configuration/#onPush') event to perform actions when data changes are pushed to a store.
 - The **push** method does not modify the remote data source. It is used to push changes from the data source to the local store without reloading data.
+- To update nested data, specify `changes.data` as a nested object:
+
+        store.push([{ type: "update", data: { Address: { City: "Bentonville" } }, key: key }]);

-After being notified, the **DataSource** can reapply sorting, filtering, grouping, and other data processing settings if you set the [reshapeOnPush](/api-reference/30%20Data%20Layer/DataSource/1%20Configuration/reshapeOnPush.md '/Documentation/ApiReference/Data_Layer/DataSource/Configuration/#reshapeOnPush') property to **true**.
