NativeScript one-way databinding doesn't update view
<p>This seems like a pretty simple case to me, but I'm obviously missing something.  I have a Model to be bound to the View.  I then load the Model with an Http call.  Why doesn't the View update?  I thought that was the whole point of one-way binding.</p>

<p>I have verified that I'm getting back the data I'm expecting from the http call.</p>

<p><strong>Update</strong>
I added a button to the screen and databinding will actually update the screen with the http loaded data for both fields on button push, even though the button method only sets one of the values.  So either there's a bug in NativeScript or I'm not doing something incorrectly.</p>

<p><strong>Update 2</strong> Just the act of clicking the button will trigger the binding to happen.  I've modified the code to have an empty tap handler, and just clicking the button makes it bind.</p>

<p>typescript</p>
