Update column render function to be raw output

Is it okay to make this change?

I'm trying to prepend a dollar sign to a column value through a custom render:
'render' => 'function(data, type, full) { return "$"+data }'

The quotes ensure the dollar is a string value, but they get encoded causing js errors so I need output render as raw.
As render is always going to be a function I figured this was okay but changing things to output raw always makes me paranoid
