Simplest way to call a controller method from a view button in .Net (mvc)

I just started programming at MVC and I would like to ask about the best way to call a controller's method from your view. To make it easier: I have a model called Song with 2 methods to start and stop it:

public class Song
{
        WMPLib.WindowsMediaPlayer wplayer ;

        public Song() {
            wplayer = new WMPLib.WindowsMediaPlayer();
            wplayer.URL = "my song url";
            wplayer.controls.stop();
        }
        public void Stop() {
            wplayer.controls.stop();
        }
        public void Start() {
            wplayer.controls.play();
        }
    }

In the controller I create the song object and I have two functions to start and stop it.

public class DefaultController : Controller
        {
            // GET: Default
            Song c = new Song();

            public ActionResult Index()
            {
                return View(c);
            }
            public void Start() {
                c.Start();            
            }
            public void Stop() {
                c.Stop();
            }
        }

In the view I have 2 buttons that correspond to each controller action.

<button type="button">Start</button>
<button type="button">Stop</button>

How can I do the most correct way to call each controller action from the view buttons?

Thank you very much for your attention, I appreciate your help
