/**
* Binds an existing control group to a DOM element.
*
* ### Example ([live demo](http://plnkr.co/edit/jqrVirudY8anJxTMUjTP?p=preview))
*
* In this example, we bind the control group to the form element, and we bind the login and
* password controls to the login and password elements.
*
* ```typescript
* @Component({
* selector: 'my-app',
* template: `
* <div>
* <h2>NgFormModel Example</h2>
* <form [ng-form-model]="loginForm">
* <p>Login: <input type="text" ng-control="login"></p>
* <p>Password: <input type="password" ng-control="password"></p>
* </form>
* <p>Value:</p>
* <pre>{{value}}</pre>
* </div>
* `,
* directives: [FORM_DIRECTIVES]
* })
* export class App {
* loginForm: ControlGroup;
*
* constructor() {
* this.loginForm = new ControlGroup({
* login: new Control(""),
* password: new Control("")
* });
* }
*
* get value(): string {
* return JSON.stringify(this.loginForm.value, null, 2);
* }
* }
* ```
*
* We can also use ng-model to bind a domain model to the form.
*
* ```typescript
* @Component({
* selector: "login-comp",
* directives: [FORM_DIRECTIVES],
* template: `
* <form [ng-form-model]='loginForm'>
* Login <input type='text' ng-control='login' [(ng-model)]='credentials.login'>
* Password <input type='password' ng-control='password'
* [(ng-model)]='credentials.password'>
* <button (click)="onLogin()">Login</button>
* </form>`
* })
* class LoginComp {
* credentials: {login: string, password: string};
* loginForm: ControlGroup;
*
* constructor() {
* this.loginForm = new ControlGroup({
* login: new Control(""),
* password: new Control("")
* });
* }
*
* onLogin(): void {
* // this.credentials.login === 'some login'
* // this.credentials.password === 'some password'
* }
* }
* ```
