hope this fix your issue After days do this and that, i can provide a workaround. Despite add the EventHandler to the Cell i add it to the DataGrid itself, then the Method which Handle the event should identify the cell that raise the event
add the EventHandler
code :
while (Reader.Read())
{
    var Name = UppercaseWords(Reader.GetString(0));
    kelasSelect.Rows.Add(Name);
}
Reader.Close();
classSelect.CellMouseUp += FormCaller;
protected internal void FormCaller(object sender, EventArgs e)
{
   DataGridView Sender = (DataGridView)sender;
   string FormName = Sender.CurrentCell.Value.ToString(); //This is how i identify the cell who raise the event
   NForm = new myForm(this);
   NForm.Text = FormName;
}

Hope that helps The button you are adding shares the DataContext from the current row in the DataGrid, so when you call 'MyCommand', WPF searches the object in TOR_List, and as it probably does not exists, it will not execute. You can check the output windows to check for binding errors.
To achieve what you want, you'll have to create the command in the object from which TOR_List is a list for, or use RelativeSource.

seems to work fine Hey no need of checking time and all just Rebind the gridview after each data/row adding.
like
code :
//Code to bind gridview
Dataset dst=yourFunctionToGetRequiredTableRows();
yourGridView.DataSource=dst;
yourGridView.Databind();
protected void Button2_Click(object sender, EventArgs e)
    {
        SqlConnection connection = new SqlConnection("Data Source=RGUNASEL-   DESK\\SQLEXPRESS;Initial Catalog=eLogbook;User ID=sa;Password=1234");
        connection.Open();
        SqlCommand cmd = new SqlCommand("eform2", connection);
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.Add(new SqlParameter("@lot_num", SqlDbType.VarChar, 50)).Value = TextBox8.Text;
        cmd.Parameters.Add(new SqlParameter("@location", SqlDbType.VarChar, 50)).Value = TextBox9.Text;
        cmd.Parameters.Add(new SqlParameter("@total_in", SqlDbType.VarChar)).Value = TextBox10.Text;
        cmd.Parameters.Add(new SqlParameter("@first_test", SqlDbType.VarChar, 50)).Value = TextBox11.Text;
        cmd.Parameters.Add(new SqlParameter("@second_test", SqlDbType.VarChar)).Value = TextBox12.Text;
        cmd.Parameters.Add(new SqlParameter("@third_test", SqlDbType.VarChar, 50)).Value = TextBox13.Text;
        cmd.Parameters.Add(new SqlParameter("@total_out", SqlDbType.VarChar, 50)).Value = TextBox14.Text;
        cmd.Parameters.Add(new SqlParameter("@lot_status", SqlDbType.VarChar, 50)).Value = TextBox17.Text;
        cmd.Parameters.Add(new SqlParameter("@remark", SqlDbType.VarChar, 50)).Value = TextBox16.Text;

        cmd.ExecuteNonQuery();
        //Response.Write("Submitted!");

        //Code to bind gridview
        Dataset dst=yourFunctionToGetRequiredTableRows();
        yourGridView.DataSource=dst;
        yourGridView.Databind();

    }
public Dataset yourFunctionToGetRequiredTableRows()
{
 Dataset dst=new Dataset();
 //"your SQL SELECT statement here".
 return dst;
}

To fix the issue you can do You need to initiate binding to appropriate property from your button:
code :
 <Button Name="btnEdit"
            Content="Edit"
            IsEnabled="{Binding DataContext.ActivationStatus, Converter={StaticResource MyStatusToBooleanConverter}, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type DataGridRow}}}" />

I wish did fix the issue. If your DataGridView is not populated with data bindings, why not creating the DataGridViewButtonColumn at design time instead of runtime?
Otherwise, you can just check if the column already exist with dgConditions.Columns.Contains("Remove")

To fix the issue you can do You can try using DataTemplate Triggers and set needed property inside it. For example, if Availability is a property in DataContext of DataTemplateColumn, it will look nearly like this:
code :
<DataGridTemplateColumn.CellTemplate>
  <DataTemplate>
     <Button x:Name="deployBtn" Click="deployBtn_Click" Height="25" Width="45" Background="#FF43B46C"  Margin="0 -3 0 0">
     //...your code
     </Button>
  <DataTemplate.Triggers> 
     <DataTrigger Binding="{Binding DataContext.Availability RelativeSource={RelativeSource AncestorType=DataTemplateColumn}}" Value="Unavailable">
        <Setter Property="IsEnabled" TargetName="deployBtn" Value="False"/>
     </DataTrigger>
  </DataTemplate.Triggers>
  </DataTemplate>
