can-value when cross-bound with input value using === comparison

[machellerogden]

Possible bug found involving can-value. It seems that when cross-bounding with an input value a === comparison is being applied.

For example, given the following...

<input name="style" type="radio" can-value="styleId" value="{{id}}" />

If id is a Number and styleId is a String at the time the component initializes, these values will not be properly cross-bound.

I'll try to follow-up with a pull request shortly.
