Run Function when @Html.CheckBox is clicked c#

I have a list of checkboxes and I want to run a function when they are clicked.

<table class="table">
    <tr>
        <th>
            @Html.DisplayNameFor(model => model.RequiresSetup)
        </th>
    </tr>

    @foreach (var item in Model)
    {
        <tr>
            <td>
                @Html.CheckBox("RequiresSetup", item.RequiresSetup) 
            </td>
        </tr>
    }
</table>

So far I am using @Html.CheckBox(String, bool), but this is not enough. After checking the InputExtensions.CheckBox Method Documentation I also do not see a way out of it.

I want to detect when a user checks or unchecks a certain checkbox, so I can call a function that immediatly saves the change in the database.

After my research I also believe I need something like this:

void Handle_Clicked(Object sender, EventArgs e) {
    //save to DB
}

But I have no idea on how to tell CheckBox "i" to that that funcion accordingly.

How do I proceed?

As it's ASP.Net MVC (and not webforms) you can't write server-side events. Instead, what you should do is catch the "click" event using javascript, then make an AJAX call (POST) to execute an action in a controller.

For example here is how you would catch the event client side using JQuery: https://stackoverflow.com/a/3442342/870604

And here is an example of an AJAX call to execute an action on your controller: Proper way to use AJAX Post in jquery to pass model from strongly typed MVC3 view
