How to refresh createdrow after edititing ?

Hello everybody, I had used createdrow in order to affect a classname for some rows depending from values. My problem is after editind a row with editor tools, the class didn't keep affect.

my code :

"createdRow": function ( row, data, index ) {
        /* ajout des classes de label a la colonne état (colonne 6)*/
        var dataEtatQualite = data.qualite.etat;
        var classLabel = data.configurationEtats[dataEtatQualite].class;
        $('td:eq(6)', row).html( '<span class="label ' + classLabel + '">' + dataEtatAction + '</span>' );
    }

It works perfectly when loading the datatable but not after editing. Thanks a lot for your help.
