StackLayout update

Hi,

I have this code, where I loop through an array and make a grid and add it to the StackLayout, and then when you click one it takes you to the next page..

using System;
using Newtonsoft;
using Newtonsoft.Json.Linq;
using Xamarin.Forms;

namespace App
{
    public class PendingChats : ContentPage
    {
        //public StackLayout sl;
        //public ScrollView scroll; 
        public static bool NotAccepted = false; 
        public static PendingUsers[] pendingUserList = DependencyService.Get<GetPendingChats>().ListChats(DataAccess.Url + ?sso=" + DataAccess.SSOToken + "&action=pendingchats");
        public static int UserSelected = 0; 
        public PendingChats () {

            ScrollView scroll = new ScrollView ();


            Title = "Pending Chats";

            Content = scroll;

            scroll.Content = DrawList();
        }

        public StackLayout DrawList() { 

            PendingUsers[] pendingUserList = DependencyService.Get<GetPendingChats>().ListChats(DataAccess.Url + ?sso=" + DataAccess.SSOToken + "&action=pendingchats");
            StackLayout stack = new StackLayout { 
                Spacing = 0,
            };
            stack.Children.Clear ();
            for (int i = 0; i < pendingUserList.Length; i++) {
                Grid g = new Grid { RowSpacing = 0, Padding = new Thickness(10, 5, 10, 5), ClassId = i.ToString() };
                g.ColumnDefinitions.Add (new ColumnDefinition { Width = new GridLength (1, GridUnitType.Star) });
                g.RowDefinitions.Add (new RowDefinition { Height = new GridLength (25, GridUnitType.Absolute) });
                g.RowDefinitions.Add (new RowDefinition { Height = new GridLength (25, GridUnitType.Absolute) });
                g.RowDefinitions.Add (new RowDefinition { Height = new GridLength (5, GridUnitType.Absolute) });
                g.RowDefinitions.Add (new RowDefinition { Height = new GridLength (1, GridUnitType.Absolute) });
                g.Children.Add (new BoxView { BackgroundColor = Color.White }, 0, 0); 
                g.Children.Add (new BoxView { BackgroundColor = Color.White }, 0, 1); 
                g.Children.Add (new Label { Text = pendingUserList[i].visitor_name, VerticalOptions = LayoutOptions.Center, TextColor = Color.Black }, 0, 0);
                g.Children.Add (new Label { Text = pendingUserList[i].timestamp, HorizontalOptions = LayoutOptions.End, VerticalOptions = LayoutOptions.Center, TextColor = Color.Black }, 0, 0);
                g.Children.Add (new Label { Text = pendingUserList[i].question, VerticalOptions = LayoutOptions.Center, TextColor = Color.FromHex("98989B") }, 0, 1);
                g.Children.Add (new BoxView { BackgroundColor = Color.White }, 0, 2);
                g.Children.Add (new BoxView { BackgroundColor = Color.FromHex("CBCBCE") }, 0, 3);
                stack.Children.Add (g);
                var GridTap = new TapGestureRecognizer();
                GridTap.Tapped += (s, e) => {
                    NotAccepted = true;
                    UserSelected = Convert.ToInt32(g.ClassId);
                    Navigation.PushAsync(new Chat(pendingUserList[Convert.ToInt32(g.ClassId)].sessionid)); 
                    NotAccepted = false; 
                };
                g.GestureRecognizers.Add(GridTap);
            }
            return stack;

        }



    }
}

But I go to the next page, Click a button and it returns back here.. however the list hasn't updated but when i breakpoint through it the array does have the item which has been deleted out of it and when I reboot the app its how it should be
