Framework7 : After completed rendering event

I am building a mobile app that calls API and render response data received from server.
The template is quite simple

	<!-- template -->
	{{#each customers}}
		<!-- render each customer -->

	return {
		methods: {
			getData: {
				const self = this;
				app.request.get('').then((res) => {
					self.$setState({customers: res.customers});
		on: {
			pageBeforeIn: function() {

I need to perform a logic after the page is completely rendered with data received from server (for example, refreshing scroll)
Is there any event that triggers when the page is completed rendered?
$update() returns a promise but it seems to me that the promise is not resolved when the page is finished rendering.
