Create from xaml DataGridTemplateColumn column in c#

I have short xaml code :

<DataGridTemplateColumn>
     <DataGridTemplateColumn.CellTemplate>
          <DataTemplate>
               <TextBlock Text="{Binding Category}"></TextBlock>
           </DataTemplate>
      </DataGridTemplateColumn.CellTemplate>
      <DataGridTemplateColumn.CellEditingTemplate>
          <DataTemplate>
                <TextBox Text="{Binding Category}" KeyUp="TextBox_KeyUp"></TextBox>
          </DataTemplate>
      </DataGridTemplateColumn.CellEditingTemplate>
</DataGridTemplateColumn>

But I dont know how to convert it on c#. I did that: but it dont work, and dont know how add Event to TextBox:

Edit: dont throw exception, but still dont work. Without event.

var a = new DataGridTemplateColumn() { Header = "Kategoria", Width = new DataGridLength(1, DataGridLengthUnitType.Star) };
var aa = new DataTemplate();
aa.Resources.Add(1, new TextBlock() { Text = new Binding("Category").ToString() });
a.CellTemplate = aa;
var aaa = new DataTemplate();
aaa.Resources.Add(2, new System.Windows.Controls.TextBox() { Text = new Binding("Category").ToString() });
a.CellEditingTemplate = aaa;
ProjectDataGrid.Columns.Add(a);
ProjectDataGrid.Columns.Add(new DataGridTextColumn() { Header = "Mnemonik", Binding = new Binding("Mnemoniese"), Width = new DataGridLength(1, DataGridLengthUnitType.Star) });

I think it might be helpful. I just convert your XAML markup in C# code step by step.

DataGridTemplateColumn templateColumn = new DataGridTemplateColumn
{
    CellTemplate = new DataTemplate
    {
        DataType = typeof(TextBlock)
    },
    CellEditingTemplate = new DataTemplate
    {
        DataType = typeof(TextBox)
    }
};

FrameworkElementFactory CategoryBlock = new FrameworkElementFactory(typeof(TextBlock));
CategoryBlock.SetBinding(TextBlock.TextProperty, new Binding("Category"));
templateColumn.CellTemplate.VisualTree = CategoryBlock;

FrameworkElementFactory CategoryTextBox = new FrameworkElementFactory(typeof(TextBox));
CategoryTextBox.SetBinding(TextBox.TextProperty, new Binding("Category"));

CategoryTextBox.AddHandler(KeyUpEvent, new KeyEventHandler(TextBox_KeyUp));
templateColumn.CellEditingTemplate.VisualTree = CategoryTextBox;

ProjectDataGrid.Columns.Add(templateColumn);
