AJAX :: Animation Extender In A Repeater Control?

i have an animationExtender control inside a repeater control. targetcontrol of the animationextender is a linkbutton. which should enabled=false when the animation is playing. simply the link button should disabled when the mouseover event of the link button. and after the animation is closed the same link button should be enabled. the problem is this is working fine only for the very first item in the repeater control. i.e. for the first link button in the repeater control when the animation is played the link buttons becomes disabled.(this happens for every link button in the repeater control) but when the animation is closed the first link button becomes enable. but in other link buttons, it remains as disabled.

I'll put the code here:

<asp:Repeater ID="repRecentJobs" runat="server" >
<ItemTemplate>
<div>
<asp:LinkButton runat="server" ID="lnkTitle" Text='<%# Eval("Title") %>' ></asp:LinkButton>
<div><%# Eval("Description") %></div>
<asp:HiddenField runat="server" ID="hfJobId" Value='<%# Eval("Id") %>' />
<asp:LinkButton runat="server" ID="readMore" Text="Read More..." ></asp:LinkButton>
<ajaxToolKit:AnimationExtender ID="AnimationExtender1" runat="server" TargetControlID="readMore">
