Problem when getting data via ajax - framework7

The ajax query to a php file of up to 150 records does fine, when it exceeds this number of records, when fetching the data and drawing it to the DIV, this problem occurs.

{
    path: '/lazy-load/:Page',
    url: './pages/lazy-load.php',
	name:'productos',
	options: { transition: 'f7-dive', },
	on: {
        pageAfterIn: function (e, page) {
		},
		pageBeforeIn: function (e, page) {
        },
        pageInit: function (e, page) {
		
		var jsonData= JSON.parse(localStorage.getItem("dataUser"));
		//alert(jsonData.name);
		var referencia=this.id;
		var user = jsonData.id_usuario;
		var idBusiness = jsonData.idBusiness;
			
		var page_view	=	app.view.main.router.currentRoute.params.Page;
		app.request.post('/ajax-post/productos/productos.php', { categoria: page_view,user:user,idBusiness:idBusiness }, function (data) {
		$$('#div-productos').html(data);
		$$('.title').html(page_view);
		});
		
		$$('.page').addClass('page-lazy-load');

									},
		lazyLoad: function (el) {
				console.log(el);
			},
			lazyLoaded: function (el) {
				console.log(el);
			},
			lazyError: function (el) {
				console.log(el);
			},
      },
  },
