Vue: The problem of radio and v-model?

[cnx2016]

I bind two radio elements with v-model. When the radio elements were clicked, I want to get a boolean result, but the real result is String TYPE?!

This is my codes:

Use v-bind

This is much later, but I was having a similar issue while testing Vue with DOM templates and CDN inclusion of Vue.

Is it possible to get an explanation of why utilizing v-bind on the value is a fix for this, and why the boolean true/false gets changed into a string if not bound? I tried to step through with debugger but was unable to.

@mgrollins By default, DOM attributes are string. If v-bind is not used, Vue won't override this behavior.
