jQuery

I am using jquery tab in asp.net application, I am displaying some asp.net controls in it. The problem arising is that after I click submit button,the tab control stops working and displays the tabs as hyperlink.
This is how I am making tabs

$(function () {
    $("#myTabs").tabs();
});

This is my HTML

    <div id="myTabs">
        <ul>
            <li><a href="#info">My Info</a></li>
            <li><a href="#account">My Account</a></li>
        </ul>
        <div id="info" >
</div>
<div id="account">
</div>
<div>

This is my submit button

<asp:Button runat="server" ID="btnsave" OnClick="btnsave_Click" Text="Save" />

When I submit the form, These two anchors display as normal anchors and there is no error in developer's tool.

What I have tried:

I have checked the source of page by clicking View source, Jquery, jquery ui and its css reference is there even after post back.
