Render values with val. Fixes #1828

In jQuery 1.9, setting the value of an input with
`attr(` is no longer supported. Here we explode
`applyAttributeBindings` to handle value properties
with `val(` instead. of `attr(`. This required adding

Some regression tests where added, to prevent this in the future.
