Ich habe einige einfache eckige 2-Komponenten mit Vorlage. Wie lösche ich das Formular und alle Felder nach dem Absenden? Ich kann die Seite nicht neu laden. Nach dem Einstellen der Daten mitdate.setValue('') field is stiltouched.

import {Component} from 'angular2/core';
import {FORM_DIRECTIVES, FormBuilder, ControlGroup, Validators, Control} from 'angular2/common';

@Component({
    selector: 'loading-form',
    templateUrl: 'app/loadings/loading-form.component.html',
    directives: [FORM_DIRECTIVES]
})

export class LoadingFormComponent {
    private form:ControlGroup;
    private date:Control;
    private capacity:Control;

    constructor(private _loadingsService:LoadingsService, fb:FormBuilder) {
        this.date = new Control('', Validators.required);
        this.capacity = new Control('', Validators.required);
        this.form = fb.group({
            'date': this.date,
            'capacity': this.capacity
        });
    }

    onSubmit(value:any):void {
        //send some data to backend
    }
}

loading-form.component.html

<div class="card card-block">
    <h3 class="card-title">Loading form</h3>

    <form (ngSubmit)="onSubmit(form.value)" [ngFormModel]="form">
        <fieldset class="form-group" [class.has-danger]="!date.valid && date.touched">
            <label class="form-control-label" for="dateInput">Date</label>
            <input type="text" class="form-control form-control-danger form-control-success" id="dateInput"
                   min="0" placeholder="Enter loading date"
                   [ngFormControl]="form.controls['date']">
        </fieldset>
        <fieldset class="form-group" [class.has-danger]="!capacity.valid && capacity.touched">
            <label class="form-control-label" for="capacityInput">Capacity</label>
            <input type="number" class="form-control form-control-danger form-control-success" id="capacityInput"
                   placeholder="Enter capacity"
                   [ngFormControl]="form.controls['capacity']">
        </fieldset>
        <button type="submit" class="btn btn-primary" [disabled]="!form.valid">Submit
        </button>
    </form>
</div>
