Sorting columns in data table

I have a table with column having values for
Ex : <td align="center">{100,002,001|number_format:0:".":","} </td>
I am trying to sort it by using
{key:"Value", parser:"datatype-number"},
for column defs
{key:"Value", sortable:true},
But sorting does not work in right way even after clickin couple of times.
I am assuming its becoz I have comma in the value.
Is there any way get it sorted??
