ASP.NET WebForms, how to call a server method from javascript

I want to execute a method from a server side. I am using ASP.NET WebForm. I am subscribed to a button click dynamically with jquery

$('input[value="execute"]').bind("click", myJavaScriptFunction);

I am not using this way

<asp:Button ID="btnSend" runat="server" CssClass="modalButton" Text="execute" OnClick="btnSend_Click" />

because I want to display a confirm dialog before the execution of the click event if OK button was pressed

var myJavaScriptFunction = function (e)
{
    if (window.confirm('Are you sure?')) {
        //HERE I WANT TO PERFORM A CALL TO btnSend_Click with null, null PARAMETERS
    }
}

Can I do the same behavior in a different way?
