magento2 – How to get column data in Magento 2 backend knockout js

I added a custom theme to a custom admin order grid column, i loaded this theme with a knockout js file:

   return Column.extend({
        defaults: {
            bodyTmpl: 'Qxs_SerialCode/grid/cells/serialcode',
            sortable: false,
            draggable: false,
            actions: (),
            rows: (),
            rowsProvider: '',
            fieldClass: {
                'data-grid-actions-cell': true
            },
            templates: {
                actions: {}
            },
            imports: {
                rows: ''
            },
            listens: {
                rows: 'updateActions'
            }
        }
    }

However I want to edit the contents of this column with javascript, what variable could i use to retrieve the column contents?
