How to add icons to a TextField with NativeScript like you can see on the image: [here](http://sstatic.net/Sites/stackoverflow/img/error-lolcat-problemz.jpg)

My xhtml code:

```
<StackLayout>
<Image src="res://logo_login" stretch="none" horizontalAlignment="center"></Image>

<TextField #username class="input" hint="GEBRUIKERSNAAM" [(ngModel)]="user.username" autocorrect="false" 
autocapitalizationType="none"></TextField>
<TextField #password class="input" hint="PASWOORD" secure="true" [(ngModel)]="user.password"></TextField>

<Button class="btn btn-primary btn-login icon" text="\e912 INLOGGEN" (tap)="login()"></Button>

<button  class="btn btn-forgot-pass" text="PASWOORD VERGETEN?" (tap)="forgotpass()"></button>

```
