How to make a server call on tab click in bootstrap in asp.net

I have created a tab in ASP.Net using Bootstrap.

<div>
    <ul class="nav nav-tabs" role="tablist">
        <li role="presentation" class="active">
            <a href="#divrecentQ" id="linkdivrecentQ" aria-controls="divrecentQ" role="tab" data-toggle="tab">
                Recent Questions
            </a>
        </li>
        <li role="presentation">
            <a href="#divpriorityQ" aria-controls="divpriorityQ" role="tab" data-toggle="tab">
                Priority Questions
            </a>
        </li>
    </ul>

    <div class="tab-content">
        <div role="tabpanel" class="tab-pane fade in active" id="divrecentQ">
            ...Recent
            <div role="tabpanel" class="tab-pane fade" id="divpriorityQ">
                ..Priority.
            </div>
        </div>

I want to make a server call on click of tabs, but since it is in data-toggle mode, it can't fire anything on server side. I tried to make a call using jQuery.

<script>


    $("#linkdivrecentQ").click(function () {

        alert($(this).attr('id'));
        loadimages($(this));
        $.ajax({
            type: 'POST',
            url: '<%= ResolveUrl("~/amain.aspx/LoadImages") %>',
            data: '{ }',
            contentType: 'application/json; charset=utf-8',
            dataType: 'json',
            success: function (msg) {
                alert(msg.d)
            }
                    });
    });

</script>

For the code in server side:

public static void LoadImages()
{
    log.Debug("LoadImages is called");
}

But server code is not called. Thanks for your help.

Use this:

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true"></asp:ScriptManager>
<div> 
                <!-- Nav tabs -->
                <ul class="nav nav-tabs" role="tablist">
                    <li role="presentation" class="active"><a href="#divrecentQ" id="linkdivrecentQ" onclick="GetCurrentString();" aria-controls="divrecentQ" role="tab" data-toggle="tab">Recent Questions</a></li>
                    <li role="presentation"><a href="#divpriorityQ" aria-controls="divpriorityQ" role="tab" data-toggle="tab">Priority Questions</a></li>
                </ul>

                <!-- Tab panes -->
                <div class="tab-content">
                    <div role="tabpanel" class="tab-pane fade in active" id="divrecentQ">
                        ...Recent
                    </div>
                    <div role="tabpanel" class="tab-pane fade" id="divpriorityQ">..Priority.</div>

                </div>
            </div>

jquery function for the GetCurrentString function in #linkdivrecentQ anchor:

   function GetCurrentString() {
        $.ajax({
            type: "POST",
            url: "Default.aspx/GetCurrentString",
            data: '{name : "pandey" }',
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: OnSuccess,
            failure: function (response) {
                alert(response.d);
            }
        });
    }

function OnSuccess(response) {
    alert(response.d);
}

here GetCurrentString is method in the server code

[System.Web.Services.WebMethod]
    public static string GetCurrentString(string name)
    {
        return "vishal "+name;
    }
