Tabbed views is loading all pages in same time


I am using routable tabs with cordova. When I open the app all pages are getting loaded in same time.
Is there a way to load only when I press to open that tab?

var app = new Framework7({
routes:  [
    path: '/',
    url: './index.html',
on: {
    init: function () {
      var f7 = this;
      if (f7.device.cordova) {
