asp.net TextBox not updating in IE11 - asp.net

Question

I have migrated my .net projet from framework 3.5 to 4.5 and my the site was previously running under IE7.
I need to run it under IE11 now. I have a page which upon selecting an element in a dropdown display the values of the element selected.
The element has 3 different fields:
Code, name and info et a button delete which upon clicking delete the element and empty the fields.
Below is the code which does the reset:
protected void LB_Supprimer_Click(object sender, System.EventArgs e)
{
if ( this.DBDelete_TRF() )
{
this.TB_NOM.Text = "" ;
this.TB_CODE.Text = "" ;
this.TB_ACTCORR.Text = "" ;
}
MngMessage.refresh();
}
Code in aspx:
<TABLE id="Table1" borderColor="lightgrey" cellSpacing="5" cellPadding="0" width="100%"
border="0">
<TR>
<TD style="WIDTH: 168px; HEIGHT: 19px" align="right">
<asp:Label id="Lbl_code" runat="server" CssClass="label" DESIGNTIMEDRAGDROP="47">Code : </asp:Label></TD>
<TD style="WIDTH: 403px; HEIGHT: 19px">
<asp:TextBox id="TB_CODE" runat="server" Width="96px" CssClass="txt" DESIGNTIMEDRAGDROP="73"
ToolTip="Code" Font-Bold="True" ontextchanged="TB_CODE_TextChanged"></asp:TextBox>
</TD>
</TR>
<TR>
<TD style="WIDTH: 168px; HEIGHT: 68px" align="right">
<asp:Label id="Label_Nom" runat="server" CssClass="label" DESIGNTIMEDRAGDROP="86">Nom : </asp:Label></TD>
<TD style="WIDTH: 403px; HEIGHT: 68px">

Font-Bold="True" TextMode="MultiLine" Rows="4"></asp:TextBox></TD>
</TR>
<TR>
<TD style="WIDTH: 168px" align="right"></TD>
<TD style="WIDTH: 403px">
<asp:Label id="LB_INFO" runat="server" CssClass="label">Info</asp:Label></TD>
</TR>
<TR>
<TD style="WIDTH: 168px" align="right">
<asp:Label id="Label8" runat="server" CssClass="label" DESIGNTIMEDRAGDROP="49">Action : </asp:Label>
<asp:CheckBox id="chk_Confirmee" runat="server" CssClass="DBLabel" ToolTip="xxx yyy"
Text="Confirmée"></asp:CheckBox></TD>
<TD style="WIDTH: 403px">
<asp:TextBox id="TB_ACTCORR" runat="server" Height="74px" Width="360px" CssClass="txt" TextMode="MultiLine"
Rows="5"></asp:TextBox></TD>
</TR>
<TR>
<TD align="center" height="15"><cc1:linkbutton id="LB_Supprimer" runat="server" DisableText="Traitement en cours" DisableAfterClick="True" onclick="LB_Supprimer_Click">Supprimer</cc1:linkbutton></TD>
</TR>
</TABLE>
The above does not work in IE11 only but in chrome it does.
Any idea how to solve this pls?
