FlowListView "FlowLoadingCommand" is not being called

I have implemented daniel luberda's FlowListView, and am trying to make an infinite loading FlowListView. However, for some reason I cannot get the loading command to get called, and I cannot seem to figure out why.

I have an ICommand implementation:
"public ICommand LoadingCommand
{ get; private set;}"

Which is begin set in the VM's contructor
"LoadingCommand = new Command(async () =>
{
await LoadMoreAsync();
});"

And the method itself looks like this:
"private async Task LoadMoreAsync()
{
SQLiteConnection conn = new SQLiteConnection(App.DatabaseLocation);
conn.CreateTable();

        int startIndex = Products.Count;

        await Task.Delay(1000);

        for (int i = startIndex; i < startIndex + 2; i++)
        {
            try
            {
                Products.Add((ProductModel)(conn.Get(i, new TableMapping(typeof(ProductModel), CreateFlags.None))));
            }
            catch (System.InvalidOperationException)
            {
                System.Diagnostics.Debug.WriteLine("No more elements to load");
            }

        }
        conn.Close();

        flowIsLoadingInfinite = false;
    }"

My XAML page file looks like this:

"
