"Remove" buttons in a column

I am trying to put a button in the last column of my grid. In my data array, I have the following entry for one row:

["Automatic Bar Controls","","1","0","7/19/2002","7/19/2002",'<input name="inp33" onclick="deleteRow(this)" type="button" value="241"></input>']

and my column headers:

["Company","Desc","Amendment","Amend/Waiver","Binder Date","Due Date","Remove Button"]

Yet, although the grid works fine, as before I added the button column, no buttons appear. Can you please tell me what I am missing? I tried enclosing the entire grid code in a form, but this had no effect. Thanks.

DOH! I forgot to increment the ColumnProperty count to show the new column!
