Programmatically adding template field in ASP.NET GridView problem

I am trying to programmatically add a template field to an ASP.NET GridView control using C# code behind. I can successfully add the template field with not problem, the problem I am having is capturing events of the template.
For instance, Before adding the columns dynamically I had a column that was a template field that contained a check box.  When clicked the checkbox called some javascript that highlighted the selected row. Is their a way of still being able to do this using the dynamic method.? Any help would be greatly appreciated.
Thanks

//  Here is where I am adding the template field
protected void buildColumns(string searchType)
{
     GridViewMaterial.Columns.Clear();
 
     // Email Field
     TemplateField templateEmail = new TemplateField();
     templateEmail.ItemTemplate = new GridViewTemplate(DataControlRowType.DataRow, "test");
     templateEmail.HeaderTemplate = new GridViewTemplate(DataControlRowType.Header, "test");
     GridViewMaterial.Columns.Add(templateEmail);
}
 
// Here is the code for building the template field
public class GridViewTemplate : ITemplate
{
     private DataControlRowType templateType;
     private string columnName;
 
     public GridViewTemplate(DataControlRowType type, string colname)
     {
          templateType = type;
          columnName = colname;
     }
 
     public void InstantiateIn(System.Web.UI.Control container)
     {
          switch (templateType)
          {
              case DataControlRowType.Header:
                  CheckBox checkAll = new CheckBox();
                  checkAll.Text = "Select All";
                  checkAll.Attributes.Add("selectAll", "onclick='checkAll(this.form);'");
                  container.Controls.Add(checkAll);
                  break;
              case DataControlRowType.DataRow:
                  CheckBox cb = new CheckBox();
                  cb.ID = "emailCheckBox";
                  cb.Text = "";
                  cb.Attributes.Add("selectRow", "onclick='colorRow(this);'");
                  container.Controls.Add(cb);
                  break;
              default:
                  break;
          }
      }
}
