What is the expected behavior?

I want to create a wrapper component with md-form-field which render a dynamic component that render and (input, checkbox ...).

    <md-form-field>
      <ng-template #fieldComponent></ng-template> // will render a component with `<input mdInput />` for example
    </md-form-field>

What is the current behavior?

An exception is raised Error: md-form-field must contain a MdFormFieldControl.

What are the steps to reproduce?

Providing a Plunker (or similar) is the best way to get the team to see your issue.
Plunker template: https://goo.gl/DlHd6U

What is the use-case or motivation for changing an existing behavior?

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

Is there anything else we should know?
