I am using `FormBuilder` and have simple validation which checking if field is valid with `*ngIf="!field.valid`

```
<input [ngFormControl]="myForm.controls['field']"
       type="text" id="field"  #field="ngForm">
<span class="error" *ngIf="!field.valid">Error</span>

```

Always when components are loaded the `errors` are shown before I even type anything in any inputs. How to stop Angular 2 of running validation on component load so it fires only when typing?
