Error in sending parameters to controller through @Url.Action in JQuery

Question

I am working on an MVC project and I was trying to send some parameters to my controller in JQuery using @Url.Action.

HTML code:

<button class="btn btn-white btn-sm demo1" data-id='@item.TeamID'>Delete</button>

JQuery Code:

    $(document).ready(function () {
        $('.demo1').click(function (event) {
            swal({
                title: "Are you sure?",
                text: "You will not be able to recover this team!",
                type: "warning",
                showCancelButton: true,
                confirmButtonColor: "#DD6B55",
                confirmButtonText: "Yes, delete it!",
                closeOnConfirm: false
            }, function () {
                var data = event.data;
                var id = data.id;
                var url = '@Url.Action("Delete", "Teams", new { id = "__param__" })';
                window.location.href = url.replace('__param__', encodeURIComponent(id));

                swal("Deleted!", "Your team has been deleted.", "success");
            });
        });
    });

However, the Delete method in the Teams controller is not being triggered. Am I missing something?

UPDATE: The HTML button is placed inside a foreach loop:

@foreach (var item in Model)
{
    <tr>
          <td>
              @Html.DisplayFor(modelItem => item.TeamName)
          </td>
          <td>
              @Html.DisplayFor(modelItem => item.TeamInits)
          </td>
          <td>
              @Html.ActionLink("Edit", "Edit", new { id = item.TeamID }, new { @class = "btn btn-white btn-sm" })
              <button class="btn btn-white btn-sm demo1" data-id='@item.TeamID'>Delete</button>
          </td>
      </tr>
 }

Use HTMLElement.dataset property or .data() to read the custom data-* prefixed attribute value.

$(document).ready(function () {
    $('.demo1').click(function (event) {            
        var id = this.dataset.id; 
        //OR
        var id = $(this).data('id');

        //Rest of the code
        swal();
    });
});
