Summing values of two textboxes in Asp.net MVC

Im new to ASP .NET MVC Web Aplications and i please need some help. I need to summ two values ("Cena" and "Kolicina") and save into textbox "Znesek". How should i do this? I tried this (How to multiply values of two textboxes in Asp.net MVC) but its not working for me :/

Here is my .cshtml file:

    <div class="form-group">
        @Html.LabelFor(model => model.kolicina, htmlAttributes: new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.EditorFor(model => model.kolicina, new { htmlAttributes = new { @class = "form-control" } })
            @Html.ValidationMessageFor(model => model.kolicina, "", new { @class = "text-danger" })
        </div>
    </div>

    <div class="form-group">
        @Html.LabelFor(model => model.cena, htmlAttributes: new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.EditorFor(model => model.cena, new { htmlAttributes = new { @class = "form-control" } })
            @Html.ValidationMessageFor(model => model.cena, "", new { @class = "text-danger" })
        </div>
    </div>

    <div class="form-group">
        @Html.LabelFor(model => model.znesek, htmlAttributes: new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.EditorFor(model => model.znesek, new { htmlAttributes = new { @class = "form-control" } })
            @Html.ValidationMessageFor(model => model.znesek, "", new { @class = "text-danger" })
        </div>
    </div>

            db.SaveChanges();
            return RedirectToAction("Index");

Try this javascript code. This should work.

$(function(){

  $("#kolicina,#cena").keyup(function(e){

  var val1=$("#kolicina").val(),
      val2=$("#cena").val(),
      result="";

  if(val1.length > 0){
    result += val1;
  }

  if(val2.length > 0){
    result += val2;
  }

  $("#znesek").val(result);

  });

});
