@Adam, using this code are you getting any error?

No errors and the UI updates on a refresh

Solution 1

You are adding the contact to the server with the ajax call I presume?
Thats why its there after a page resfresh.

In the succeshandler of the ajax call you'll need to push it into the observable array.

self.contacts.push(contact);

Now it should show up directly.

I have tried this but this add the contact to the array instead of replacing it.
i can fudge it be forcing a refresh on success
