determine button click and modify values in another button aspx.net - asp.net

Question

I have dynamically created Data Table bind to Grid View. In every row I'm adding button which i'm define in grid view. Now I want that button to call in another button click event and make modifications in values.Is that possible?Here is my code:
<asp:GridView ID="GridView2" runat="server" OnRowDataBound="GridView2_RowDataBound">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Button ID="btnTest" runat="server" CommandName="odzemi" CssClass="button2" OnClick="btnTest_Click" Text="-" Width="100px" Font-Bold="True" />
<asp:Button ID="Button15" Visible="false" runat="server" Text="Button" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
protected void btnTest_Click(object sender, EventArgs e)
{
Session["Counter1"] = newValue;
Session["Counter"] = newValue;
if (Session["Markici"] != null || Session["Markici"] != null)
{
var clickedRow = ((Button)sender).NamingContainer as GridViewRow;
var clickedIndex = clickedRow.RowIndex;
/*decimal*/ old = dtCurrentTable.Rows[clickedIndex].Field<decimal>("Kolicina");
decimal oldIznos = dtCurrentTable.Rows[clickedIndex].Field<decimal>("VkIznos");
decimal VkDanok = dtCurrentTable.Rows[clickedIndex].Field<decimal>("VkDanok");
string Cena1 = dtCurrentTable.Rows[clickedIndex].Field<string>("Cena1");
int TarifaID = dtCurrentTable.Rows[clickedIndex].Field<Int16>("TarifaID");
// decimal pocentDanok0 = 0.0m;
// decimal pocentDanok1 = 0.18m;
// decimal pocentDanok2 = 0.5m;
//int oldValue = int.Parse(old);
/* decimal*/ newValue = old - 1; //
Label37.Text = newValue.ToString();
decimal newIznos = oldIznos - Convert.ToDecimal(Cena1);
dtCurrentTable.Rows[clickedIndex].SetField("Kolicina", newValue.ToString());
dtCurrentTable.Rows[clickedIndex].SetField("VkIznos", newIznos.ToString());
}
//I want here to call btn_test click and modyfy his values

You can use the EditItemTemplate to corresponding every templatefield in gridview.
