Data Table Sorting Plugin Issue

Hello Tobias I installed your Data Table Sorting Plugin because my some of my numbers aren’t sorting properly. For example I have 12 showing up before 7.2. Or I have 1,160 show up before 800. The sorting plugin doesn’t help. I tried adding “aoColumnDefs”: [ { “sType”: “numeric-comma”, “aTargets”: [ 2, 3 ] } ] to the plugin options as instructed with 0, 1, 2, 3 as the targets but it doesn’t save properly in the plugin options.
