Hi Try this sample..
columnIndex: column which you want to change the name

XML

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication1.WebForm1" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script src="jquery.js.js"></script>
    <script type="text/javascript">

        var changeheader = function (columnIndex) {

            var grid = document.getElementById('<%= gv.ClientID %>');
            var headerCell = grid.rows[0].cells[columnIndex];
            headerCell.innerText = 'changed value';
            debugger;

        }
    </script>


</head>
<body>
    <form id="form1" runat="server">
        <asp:Button ID="btnSearch" Text="search" runat="server" OnClientClick="changeheader(0); return false;" />
        <br />
        <asp:GridView ID="gv" AutoGenerateColumns="false" runat="server">
            <Columns>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:Label ID="Label4" runat="server" Text='<%# Eval("name")%>'>
                        </asp:Label>
                    </ItemTemplate>
                    <HeaderTemplate>
                        Header Name
                    </HeaderTemplate>
