Angular 2: How to access an instance of Component FormControl inside this component?

Question

So, I read how to create custom FormControls in Angular2, but I cannot get what I am trying to fully accomplish with validation. I have a regular input control that I want to wrap in a custom component so that I can do this:

<my-control name="something" [(ngModel)]="model.something" required></my-control>

Instead of repeating this every time:

<div class="form-group has-feedback" [ngClass]="{'has-success': someInput.valid, 'has-error': someInput.invalid && someInput.dirty}">
    <label class="control-label" for="someId">{{label || 'Some Input'}}</label>
    <input type="test" class="form-control" id="someId" placeholder="Some Input" [ngModel]="value" (ngModel)="onChange($event)" name="someInput" required #someInput="ngModel" minlength="8"/>
    <span class="glyphicon form-control-feedback" aria-hidden="true" [ngClass]="{'glyphicon-ok': someInput.valid, 'glyphicon-remove': someInput.invalid && someInput.dirty}"></span>
    <div [hidden]="someInput.valid || someInput.pristine || !someInput.errors.required" class="text-danger">Some Input is required</div>
    <div [hidden]="someInput.valid || someInput.pristine || !someInput.errors.minlength" class="text-danger">Some Input must be at least 8 characters</div>
</div>

So, I implemented a custom component in the following articles on how to create custom components on the Internet:
