It seems, you are hitting the same URL on every refresh click. Sometime Windows Phone stores the request and response in cache.

If possible, you add one more parameter to your request and on every click just change the value of this parameter. You can use GUID or Unix Timestamp.

You can try like:

 private async void RefreshJSONButton_Click(object sender, RoutedEventArgs e)
    {
        this.JsonView.Text = string.Empty;
        HttpClient client = new HttpClient();
    int unixTimestamp = (int)(DateTime.Now.Subtract(new DateTime(1970, 1, 1))).TotalSeconds;

    string url =
    "http://API1 Address Here/Your queries&temp=unixTimestamp";
    string x = await client.GetStringAsync(url);
    this.JsonView.Text = x;
    client.Dispose();
    }
