ASP MVC Bootstrap Modal in Partial View

Question

As part of my shared layout, I'd like to have a modal dialog come up on a button click.

This is the my partial view with the modal dialog:

<ul class="nav navbar-nav navbar-right">
    <li>
        <button type="button" class="open-dialog btn" data-toggle="modal" data-target="#SettingsModal">Settings</button>
    </li>
</ul>

<!-- Modal -->
<div class="modal fade" id="SettingsModal" tabindex="-1" role="dialog" aria-labelledby="SettingsModalLabel">
<div class="modal-dialog" role="document">
    <div class="modal-content">
        <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                <span aria-hidden="true">&times;</span>
            </button>
        </div>
        <div class="modal-body">
            <p>Some text</p>
        </div>
        <div class="modal-footer">
            <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
            <a id="settings" class="btn btn-primary btn-sm" href="#">Save changes</a>
        </div>
    </div>
</div>
</div>

Script

<script type="text/javascript">
    $(document).on("click", ".open-dialog", function() {
        $('#settings').attr('href', $(this).data('url')); // update the link's url
    });
</script>

And the partial view's controller:

public class SettingsController : Controller
{
    public ActionResult _Settings()
    {
        return PartialView("_Settings");
    }
}

What I'm going for, is to have a button at the top of the page as part of the shared _Layout. Similar to this:

When I click the 'Settings' button, a modal dialog is supposed to come up, but when I click it now, the screen just goes dark, and I can sort of hint the modal dialog in the background. I'm not sure where in the modal I've done something wrong. Any hint is appreciated!

Try this:

$('#settings').on('show.bs.modal', function (event) {
        var button = $(event.relatedTarget);
        url = button.data('url');
        $.post(url, function (data) {
            $('.model-body').html(data);
        });
});

Action method:

public PartialViewResult Settings()
{
            if (Request.IsAjaxRequest())
            {
                // retrive your model
                return PartialView("_Settings");
            }
            return null;
}
