I don't see a RequestFactory "method call" in the snippets of code
above, such as ctx.persist(selectedExampleProxy).
Have a look at the Expenses sample, what it does is basically:
ExampleProxyRequest ctx = requestFactory.exampleProxyRequest();
dataBindingManager.edit(selectedExampleProxy, ctx);
ctx.persist(selectedExampleProxy);
so that when you driver.flush().fire(...), the persist() method will
be called/sent to the server to persist your object.
