Dynamic type coming from v-bind is ignored by v-model

[dasdeck]

Version

2.5.13

Reproduction link

https://codepen.io/dasdeck/pen/ZvOKqm?editors=1010

Steps to reproduce

set the input type via v-bind like in the codepen and use the checkbox to change the bound value.

What is expected?

the checkbox will control the value assigned in v-model

What is actually happening?

the value is not changed.

---

It seems to me that the v-bind is evaluated after v-model, thus the input is always a "textbox" e.g. the default and therefore can not be bound properly and only works for textbox and related input types. In comparison the :type="variableType" works just fine. See :

Also it worked in Vue 1.x.
This might be expected behaviour, but I could not find it mentioned anywhere.

Cheers!
