模式未使用新数据刷新

我有一个页面，其中所有数据都是从数据库动态加载并以div显示的。在每个div 上都有一个名为 View 的按钮。单击此按钮时，我调用一个方法：onclick="getdetails(this)"。此方法使用数据动态创建模态，并且工作正常。

function getdetails(par) {
    var modaldiv = '';
    var maincontent = '';
    var htourid = document.getElementById("htourid" + par.id).value;
    var hadultprice = document.getElementById("hadultprice" + par.id).value;
    var hchildprice = document.getElementById("hchildprice" + par.id).value;
    var hdescription = document.getElementById("hdescription" + par.id).value;
    var htourname = document.getElementById("htourname" + par.id).value;
    $.ajax({
        type: "GET",
        url: "xxxxxxxxxxxx" + htourid,
        dataType: "json",
        contentType: "application/json",
        success: function(data) {
            var rowcount = 1;
            for (var i = 0; i < data.GetToursDetailsimagesResult.TourImages.length; i++) {
                if (rowcount == 1) {
                    maincontent += '<div class="item active">' +
                        '<img src="' + data.GetToursDetailsimagesResult.TourImages[i].ImagePath + '" alt=""/>' +
                        '</div>';
                } else {
                    maincontent += '<div class="item">' +
                        '<img src="' + data.GetToursDetailsimagesResult.TourImages[i].ImagePath + '" alt=""/>' +
                        '</div>';
                }
                rowcount++;
            }
            modaldiv = '<div id="modal-package" class="modal fade" tabindex="-1" role="dialog" aria-hidden="true">' +
                '<div class="modal-dialog modal-lg">' +
                '<div class="modal-content">' +

                '<li class="active"><a href="#modal-tabs-package"><i class="gi gi-package"></i>Details</a></li>' +
                '</ul>' +
                '</div>' +
                '<div class="modal-body">' +
                '<div class="tab-content">' +
                '<div class="tab-pane active" id="modal-tabs-package">' +

                '<input type="hidden" id="htourid" value="' + htourid + '" />' +
                '<div class="col-lg-7">' +

                maincontent +

                '<a class="left carousel-control" href="#project-carousel" data-slide="prev">' +
                '<span>' +
                '<i class="fa fa-chevron-left"></i>' +

                '</a>' +
                '</div>' +
                '</div>' +
                '<asp:Label ID="lbldescription" Text="' + hdescription + '" runat="server"></asp:Label>' +
                '</div>' +
                '</div>' +
                '</div>' +
                '<div class="modal-footer">' +
                '<h4 class="pull-left"><span class="text-muted"><b>Adult Price: </b></span><strong class="text-primary">' +
                '<asp:Label ID="lbl_viewadultprice" Text="' + hadultprice + '" runat="server"></asp:Label></strong>/</h4>' +
                '<h4 class="pull-left"><span class="text-muted"><b>Child Price: </b></span><strong class="text-primary">' +
                '<asp:Label ID="lbl_viewchildprice" Text="' + hchildprice + '" runat="server"></asp:Label></strong></h4>' +
                '<br />' +
                '<br />' +
                '<button type="button" class="btn btn-effect-ripple btn-success" onclick="Open_Addtocart_view(this)" style="background-color: #7DC402;"><i class="fa fa-shopping-cart"></i>Add to Cart</button>' +
                '<a  class="btn btn-effect-ripple btn-danger" style="background-color: #C43902;" data-dismiss="modal">Close</a>' +
                '</div>' +
                '</div>' +
                '</div>' +
                '</div>';
            $("#modaldiv").append(modaldiv);
            $('#modal-package').modal('show');
        }
    });
}

问题是，一旦我第一次单击任何divs"查看"按钮，即使我单击任何其他视图详细信息按钮，它也会继续以模态显示相同的数据。如果我刷新页面，它会显示新数据，但同样的问题再次出现。

谁能帮我找出问题是什么以及如何解决？
