ASP.NET Bootstrap Modal - asp.net

Question

I am quite new to ASP.NET so forgive me if I have the functionality wrong.
I am working with Bootstrap and have a button within a tab and UpdatePanel which fires a Modal.
The Modal sits behind the screen and blacks out and I can't quite work out why.
If I take the UpdatePanel out, it works. I need the UpdatePanel because it is in a tab with an action CheckBox which without the UpdatePanel sends the user back to the first tab.
<div class="tab-pane fade" id="neworder">
<asp:UpdatePanel ID="up_New_Order" runat="server">
<ContentTemplate>
<div class="checkbox">
<asp:CheckBox ID="cb_Auto_Fill" runat="server" Text="Auto fill last order" CssClass="checkbox" AutoPostBack="true" OnCheckedChanged="cb_Auto_Fill_CheckedChanged"></asp:CheckBox>
</div>
<div class="col-md-6">
<!-- New Order -->
<asp:panel class="row form-group has-feedback" id="Panel2" runat="server">
<label for="inputName" class="col-lg-4 control-label">Ordered By</label>
<div class="col-lg-8">
<asp:Label ID="Label1" runat="server"></asp:Label>
<asp:TextBox CssClass="form-control" ID="tb_Ordered_By" placeholder="Customer name" runat="server"></asp:TextBox>
</div>
</asp:panel>
<asp:panel class="row form-group has-feedback" id="Panel5" runat="server">
<label for="inputSubject" class="col-lg-4 control-label">PO No/Agency</label>
<div class="col-lg-8">
<asp:TextBox CssClass="form-control" ID="tb_Po_Number" placeholder="PO No/Agency Ref" runat="server"></asp:TextBox>
</div>
</asp:panel>
<asp:panel class="row form-group has-feedback" id="Panel13" runat="server">
<label for="inputSubject" class="col-lg-4 control-label">Payment Type</label>
<div class="col-lg-8">
<asp:DropDownList ID="ddl_Payment_Type" runat="server" CssClass="form-control dropdown"></asp:DropDownList>
</div>
</asp:panel>
<asp:panel class="row form-group has-feedback" id="Panel14" runat="server" Visible="false">
<label for="inputSubject" class="col-lg-4 control-label">Upload</label>
<div class="col-lg-8">
<input type="file"
style="visibility:hidden; width: 1px;height:1px"
id='${multipartFilePath}' name='${multipartFilePath}'
onchange="$(this).parent().find('span').html($(this).val().replace('C:\\fakepath\\', ''))" /> <!-- Chrome security returns 'C:\fakepath\' -->
<input class="btn btn-primary" type="button" value="Upload File.." onclick="$(this).parent().find('input[type=file]').click();"/> <!-- on button click fire the file click event -->
<span class="badge badge-important" ></span>
</div>

<asp:panel class="row form-group has-feedback" id="Panel11" runat="server">
<label for="inputSubject" class="col-lg-4 control-label">Order Notes</label>
<div class="col-lg-8">
<asp:TextBox id="tb_Order_Notes" cssClass="form-control" TextMode="multiline" Columns="50" Rows="3" runat="server" />
</div>
</asp:panel>
</div>
<div class="col-md-6">
<!-- New Order -->
<asp:panel class="row form-group has-feedback" id="Panel7" runat="server">

<div class="row form-group">
<div class="col-lg-12">

</div>
</div>
</ContentTemplate>
</asp:UpdatePanel>
</div>
The modal sits just above my closing tag for Content and I call it with:
protected void btn_Create_Order_Click(object sender, EventArgs e)
{
lblModalTitle.Text = "Modal Title";
lblModalBody.Text = "Modal Body.";
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "myModal", "$('#myModal').modal().appendTo('body');", true);
upModal.Update();
//pnlAlertBox.Visible = true;
}
Here is the modal (I am reusing it so I know it does work).
<!-- Bootstrap Modal Dialog -->
<div class="modal fade" id="myModal" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<asp:UpdatePanel ID="upModal" runat="server" ChildrenAsTriggers="false" UpdateMode="Conditional">
<ContentTemplate>
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title"><asp:Label ID="lblModalTitle" runat="server" Text=""></asp:Label></h4>
</div>
<div class="modal-body">
<asp:Label ID="lblModalBody" runat="server" Text=""></asp:Label>
</div>
<div class="modal-footer">
<button class="btn btn-info" data-dismiss="modal" aria-hidden="true">Close</button>
</div>
</div>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</div>

I tried your code in my sample project and the bootstrap modal works correctly. I am using jquery 2.1.3
It could be that the jquery version you are using is causing the problem.
