Binds an existing control to a DOM element.
# Example
In this example, we bind the control to an input element. When the value of the input element
changes, the value of
the control will reflect that change. Likewise, if the value of the control changes, the input
element reflects that
change.
```
@Component({selector: "login-comp"})
@View({
directives: [FORM_DIRECTIVES],
template: ""
})
class LoginComp {
loginControl:Control;
constructor() {
this.loginControl = new Control('');
}
}
```
We can also use ng-model to bind a domain model to the form.
```
@Component({selector: "login-comp"})
@View({
directives: [FORM_DIRECTIVES],
template: ""
})
class LoginComp {
loginControl:Control;
login:string;
constructor() {
this.loginControl = new Control('');
}
}
```
