Listview not binding...showing empty list


I want to bind listview using model class filled data from httpclient request (json).. can anyone help me with sample code or tutorials.

Code behind
PostContentModel postContent = new PostContentModel()
                reqType = "DDDD",
                token = "TTT",
                device = "SDSDSD"

            var json = JsonConvert.SerializeObject(postContent);
            var content = new StringContent(json, Encoding.UTF8, "application/json");

            HttpClient client = new HttpClient();
            var response = await client.PostAsync("Requestsurl", content);

            newsModel objnewsModelList = new newsModel();

            if (response.IsSuccessStatusCode)    // Check the response StatusCode
                string responseBody = await response.Content.ReadAsStringAsync();
                objnewsModelList = JsonConvert.DeserializeObject<newsModel>(responseBody);
                listView.ItemSize = 100;
                listView.ItemsSource = objnewsModelList;
                listView.ItemTemplate = new DataTemplate(() => {
                    var grid = new Grid();
                    var newstitle = new Label { FontAttributes = FontAttributes.Bold, BackgroundColor = Color.Teal, FontSize = 21 };
                    newstitle.SetBinding(Label.TextProperty, new Binding("news_title"));
                    var newsdate = new Label { BackgroundColor = Color.Teal, FontSize = 15 };
                    newsdate.SetBinding(Label.TextProperty, new Binding("news_date"));

                    grid.Children.Add(newsdate, 1, 0);

                    return grid;

Xaml View
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
    <sflv:SfListView x:Name="listView"
                   ItemsSource="{Binding newsModel}"
                <Grid Padding="10">
                        <RowDefinition Height="0.4*" />
                        <RowDefinition Height="0.6*" />
                    <Label Text="{Binding news_title}" FontAttributes="Bold" TextColor="Teal" FontSize="21" />
                    <Label Grid.Row="1" Text="{Binding news_date}" TextColor="Teal" FontSize="15"/>

Hi Vijil, 
We would like to inform you that we are not clear with your requirement where you are facing the problem. Please let us know where you are facing the problem in below use cases 
  • Receiving JSON data
  • Converting JSON data to model object
  • Binding the model object to ListView
If you are facing problem in first and second use case, you need to find generic solution on your side, it is not related to ListView. We have already prepared and updated a sample already using webAPI. So, please share the model class or json data if possible, so that we can assist you further at our end.
