    Atomia.VM.sites.columns[5].render = function (data, type, row) {

        var actionData = row[5] ? JSON.parse(row[5]) : {};

        var subdomain = row[0];

        var websiteName = row[1];

        var templateData = {

            canEdit: actionData.canEdit,

            canDelete: actionData.canDelete,

            canMigrate: actionData.canMigrate,

            canInstallOCI: false,
