-<div class="alert alert-info">This example adds a dummy delay in the update/create operations to simulate an actual remote service (you can add your own, and remove that code). The addition compared to the basic example is the <code>isEditing</code> flag that determines whether to rehydrate the edit context when the delay in the EventCallback re-renders the listview and the templates. This lets you prevent re-initializing that context upon/after completing the data operation.</div>
