Input fields created with repeat.for in DOM not working with Aurelia Validation

[kvadd]

First of all, I want to thank you guys for an amazing framework! We use it for all our new projects for it's ease of use and primary your dedication to keeping standards.

However, I think I have hit a bug with Aurelia Validation plugin when repeat.for is responsible for rendering input fields that require validation.

I'm submitting a bug report

• Library Version:
  1.0.8

Please tell us about your environment:

• Operating System:
  Windows 10

• Node Version:
  6.2.1

• NPM Version:
  3.9.5

• JSPM OR Webpack AND Version
  JSPM 0.16.34

• Browser:
  all

• Language:
  TypeScript 2.0.3

Current behavior:
Input fields that are created under a repeat.for in the DOM are not detected as validated fields.

Expected/desired behavior:
Repeated input fields should be included in the binded value 'validate'

https://gist.run/?id=d21cdf00e9a3fd30c50c72f4a4b4df98

• What is the expected behavior?
  Repeated input fields should have the ability to be validated.

• What is the motivation / use case for changing the behavior?
  For example: For dynamic created forms, when getting form information from another source.

If you change this line in the gist:

<div class="form-group" repeat.for="field of fields">

to this:

<div class="form-group" repeat.for="field of fields" with.bind="$parent">

then the validation works.

Just sayin'. I'm not sure if this should be necessary or not.

It seems odd that the code change I described above would be required because without it is perfectly possible to bind to the fields in $parent. It is just the validation code that is having the problem.
