Steps to reproduce

If you use a dynamic type on an input, and the property is not called type, you'll get this warning:

vue.js:491 [Vue warn]: Property or method "type" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property. See: https://vuejs.org/v2/guide/reactivity.html#Declaring-Reactive-Properties.

And it won't work if you switch from a normal type like text to a checkbox or radio button (the special types that are in the else branch: f3fe012#diff-6eaa1698ef4f51c9112e2e5dd84fcde8R4)

Click the button (Click me) to switch the input to a checkbox, then try checking and unchecking the box. The model's value will not change.

Calling the property type works, the model's value will change: https://jsfiddle.net/nkovacs/rt9vcrj2/2/

What is expected?

Dynamic input type should work regardless of the property name.

What is actually happening?

Dynamic input type only works if the property is called type
