Add ion icon to ActionSheet buttons

1

In Ionic 2 we can use an actionsheet and add buttons, as follows:

let actionSheet = ActionSheet.create({
	title: translate.instant("userdata.actionsheet.title"),
	buttons: [
		{
			text: "text 2",
			handler: () => {
				get_image(1);
			}
		},
		{
			text: "text 1,
			handler: () => {
				get_image(2);	
			}
		}
	]
});

is it possible to add an ion-icon in a button?

If I do
text: ’ text 1 ’

the icon is not shown; instead, the webview shows the markup. The text attribute does not allow raw html.
Is there any way to achieve this?

I know I can add an css class to a button, but it’s not the same (and easy) as use the icon.
