Ajax Extension (Timer) stopped working when I retrieve value from DataTable - asp.net

Question

Currently I have an Ajax Timer which executes a function every few second. It is working perfectly fine until I tried to retrieve data from a DataTable. I have no idea why. I have tried debugging. I even placed label on the page to check.
For example the Ajax Timer:
Protected Sub Timer1_Tick(sender As Object, e As System.EventArgs) Handles Timer1.Tick
Label1.Text = DateTime.Now.ToLongTimeString()
End Sub
The datalist (the one giving the problem):
Protected Sub dlOrgProfile_ItemCreated(sender As Object, e As System.Web.UI.WebControls.DataListItemEventArgs) Handles dlOrgProfile.ItemCreated
Dim bizLayerMgmt As BlOrganizations
Dim dt As DataTable
bizLayerMgmt = New BlOrganizations()
dt = bizLayerMgmt.getOrgDetails(userId).Tables(0)
ddl = CType(e.Item.FindControl("ddlCoType"), DropDownList)
Dim value As Integer = Convert.ToInt32(dt.Rows(0)(3)) 'I have narrowed the problem to this line, if I comment this line.. everything works perfectly
ddl.SelectedValue = value
End Sub
The problem lies in the dt.Rows(0)(3). I have no idea why. I need to use it to retrieve some data from the database.
Just in case if its the front-end side.. here's the markup for the site.
<div class="content">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:Timer ID="Timer1" runat="server" Interval="1000">
</asp:Timer>
<asp:DataList ID="dlOrgProfile" runat="server" DataSourceID="odsOrgDetails"
EnableTheming="True" RepeatLayout="Flow" ShowFooter="False" ShowHeader="False">
<ItemTemplate>
<h3>
<asp:TextBox ID="txBxCoName" runat="server" Text='<%# Eval("OrgName") %>'></asp:TextBox>
<div class="ddlSelect">
<asp:DropDownList ID="ddlCoType" runat="server" DataSource='<%# listOrgType() %>' DataTextField="OrganizationType" DataValueField="OrgTypeID" >
</asp:DropDownList>
</div>
<h3>
</h3>
<a id="linkCoImg" href="upload_co_logo.aspx">
<asp:Image ID="CoImg" runat="server" ImageUrl="~/logo/org/default.png" />
<span>Change</span> </a>
<br />
<div id="description">
<textarea id="taCoDesc" rows="2" cols="1"><%# Eval("Description") %></textarea>
</div>
<br />
<asp:Label ID="lblContacts" runat="server" Text="Contacts:"></asp:Label>
<br />
<div id="contacts">
<asp:TextBox ID="tbContactOffice" runat="server" CssClass="tbContacts"></asp:TextBox>
<asp:TextBox ID="tbContactFax" runat="server" CssClass="tbContacts"></asp:TextBox>
<asp:TextBox ID="tbContactMail" runat="server" CssClass="tbContacts2"></asp:TextBox>
</div>
<br />
<asp:Button ID="btnSave" runat="server" CommandArgument='<%# Eval("OrgID") %>'
CommandName="save" Text="Save" />
</h3>
</ItemTemplate>
</asp:DataList>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
</Triggers>
<ContentTemplate>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
</div>

Okay I have resolved my own problem.. Still don't really get it why but this is what I did.. Instead of using ItemCreated, I used ItemDataBound.
Protected Sub dlOrgProfile_ItemDataBound(sender As Object, e As System.Web.UI.WebControls.DataListItemEventArgs) Handles dlOrgProfile.ItemDataBound
Dim bizLayerMgmt As BlOrganizations
Dim dt As DataTable
bizLayerMgmt = New BlOrganizations()
dt = bizLayerMgmt.getOrgDetails(userId).Tables(0)
ddl = CType(e.Item.FindControl("ddlCoType"), DropDownList)
Dim value As Integer = Convert.ToInt32(dt.Rows(0)(3))
ddl.SelectedValue = value
End Sub
