Two-Way Binding with createEntry SAPUI5

I am trying to use Two-Way binding with a v2 OData model. In the route matched of the create view I have the following code.

this.getOwnerComponent().oWhenMetadataIsLoaded.then(function() {  var oEntry = oView.getModel().createEntry("/ContactCollection");  oView.setBindingContext(oEntry);
}.bind(this));  }.bind(this));

At runtime i call the screen and update a value in the create view that is "bound" to the model.

Then in my save function I have been executing the following line in the debugger.

this.getView().getBindingContext().getObject()

The output is a blank entity will all properties set to "undefined".

While searching I found this page

So i implemented line

oView.getModel().setDefaultBindingMode(sap.ui.model.BindingMode.TwoWay);

in the route matched function above with same results.

I have also tried using

oView.unbindElement();

from the discussion here

Any help would be appreciated.
