title: Add pipe to formControlName in Angular2
body: <p>I am looking to add a number pipe to an input field in Angular2. I am using model driven forms and all my inputs have a formControlName instead of using data binding. The problem I have is <code>formControlName="number | number : '1.2-2'"</code> is not valid code.It throws an error saying formControlName cannot be found. I do not want to remove the formControlName in place of a ngModel because I am subscribing to the form inputs to do validation as the form is used. </p>
