jQuery Grid Plugin - jqGrid

Using 3.5 version.

Sql Server 2008.

Value recovered is of type decimal.

I'm experiencing a NaN column value when i try to format to type number.

When my number > 1000 without format the value looks like this in the Grid: 50000,00. I would like that is like 50.000,00. So i tried to use the number formatting.

File locale-sp.js has this statement:

formatter : {
...
        number : {decimalSeparator:",", thousandsSeparator: ".", decimalPlaces: 2, defaultValue: '0,00'},

...

}

So in my grid i wrote this:

colModel: [
..
                      { name: 'valor', index: 'valor', width: 50, align: 'right', formatter: 'number'},

..

]

BUT, the value is NaN, any help?

Thank you
