Title: Removed isolated scope, use inherited scope values

Isolated scope is not really needed, and if requested, can conflict with other directives:

```html
Error: [$compile:multidir] Multiple directives [ngConfirmField, popover] asking for
new/isolated scope on:
```

Changed the code to read directly from parent scope with `scope.$eval`. Tests pass.
