Angular 4 support

[BearandYoon]

Hello
I have autofill-event issue on iPhone/Chrome in my Angular 4 project.
I have added the autofill-event.js in my project and in my login page I can catch changeEvent when fill out email/pass input field but I can't get input value(autofilled email).

This is my code snippet.

<form [formGroup]="signInForm" (submit)="onSignIn()" (change)="onChange($event)">
          <div class="form-content">
            <div class="form-group">
              <input type="email" class="form-control input-underline input-lg" formControlName="email" id="email" placeholder="Email Address">
              <app-control-messages [control]="signInForm.controls.email"></app-control-messages>
            </div>
            <div class="form-group">
              <input type="password" class="form-control input-underline input-lg" formControlName="password" id="password" placeholder="Password">
              <app-control-messages [control]="signInForm.controls.password"></app-control-messages>
            </div>
          </div>
          <div class="action-container">
            <div class="btn-login-container">
              <button class="btn bordered-btn" type="submit"> Login </button>
            </div>
          </div>
        </form>

  onChange(event) {
    alert(this.signInForm.value.email);// I can see empty alert on my iPhone/Chrome.
  }

It doesn't work on chrome browser on iPhone.
