How to pass user input from view to a class in MVC - asp.net-mvc

Question

I imagine this must be pretty basic, but all my search results only show how to pass data the other way ( model to controller, controller to view, and then view back to controller, but nothing from controller back to model(class). I am trying to pass user input for a search parameter into the query string for an API. In the view:
<form method="post" action="~/Models/Search">
<input name="artist" placeholder="Enter artist's name" />
#{Search temp = new Search();
if (Request.Form["artist"] != null) //this method doesn't work; trying to get user response and pass it back to search class;
{ temp.Artist = Request.Form["artist"].ToLower(); } //have to hardcode search parameter at this time
}
<!--<button>Click Me</button>-->
<script>
var weather = Object();
$(document).ready(function () {
$('button').click(function () {
// var artist = $("#artist").val();
$.get("#Url.Action("SearchArtist", "Home")", function (response) {
console.log(response);
artistInfo = ko.mapping.fromJS(response); //populate the artist search object
ko.applyBindings(artistInfo);
});
});
});
The class:
public class Search
{
string artist;
public string Artist { get; set;}
public Object getArtistInfo()
{
string appID = "*************** ";
artist = "metallica";
string url = "http://developer.echonest.com/api/v4/artist/search?api_key="+ appID + "&format=json&name=" + artist + "&results=1&bucket=genre&bucket=songs";
//synchronous client;
var client = new WebClient();
var content = client.DownloadString(url);
var serializer = new JavaScriptSerializer();
var jsonContent = serializer.Deserialize<Object>(content);
return jsonContent;
}
}
The controller:
public ActionResult ArtistInfo()
{
return View();
}
public JsonResult SearchArtist()
{
Search artist = new Search();
return Json(artist.getArtistInfo(), JsonRequestBehavior.AllowGet);
}

Try to add attributes (runat="server" and id="chooseyourid") to html forms results below :
if you want to access to values in your code behinde you just need to write the id of your element like below :
/artiste.value;/
