Client side (office javascript api) vs server side (asp.net)

On the basis of this article , I created a ms sql database, including the models and controllers in a Excel Web AddIn (TaskPane)

How can I populate the contents of the table Movie in Excel?

This is the controller:

namespace DatabaseWeb.Controllers
{
    public class controllerMovie : Controller
    {
        private modelMovie db = new modelMovie();

        // GET: controllerMovie
        public ActionResult Index()
        {
            return View(db.Movies.ToList());
        }

This is the javascript (not working)

function loadSampleData() {

        var db = new Controllers.controllerMovie();

        var values = db.ActionResult;

        // Run a batch operation against the Excel object model
        Excel.run(function (ctx) {
            // Create a proxy object for the active sheet
            var sheet = ctx.workbook.worksheets.getActiveWorksheet();
            // Queue a command to write the sample data to the worksheet
            sheet.getRange("B3:D5").values = values;

            // Run the queued-up commands, and return a promise to indicate task completion
            return ctx.sync();
        })
        .catch(errorHandler);
    }
