DataTable column sorting incorrectly

I have a dataTable and I'm populating the table with data from a list.  One of my columns in the datatable is a textbox for users to manipulate.  In SharePoint, the column is a number column.  I do notice that when I sort it in the dataTable, it's not sorted correctly, even if I force it with a parseInt.  If not in a textbox, it sorts correctly. See pic below.


Any ideas how to fix?

Thanks!
