How to change deleteAction in Jtable

Question

Please tell me how to change the setting actions.deleteAction with functions deleteConfirmation that would not change the source ?
Thanks in advance!

$('#pages-table').jtable({
    title: 'Birds',
    paging: true,
    pageSize: 15, 
    sorting: true, 
    defaultSorting: 'name ASC',
    selecting: true,
    multiselect: true,
    selectingCheckboxes: true,
    selectOnRowClick: false,
    actions: {
        listAction: '/aima-admin/?plugin=pages&ajax=yes&action=jtable&jtable=list&catid=1&lang=en',
        deleteAction: '/aima-admin/?plugin=pages&ajax=yes&action=jtable&jtable=delete'
    },
    deleteConfirmation: function(data) {
        data.deleteConfirmMessage = '<p>Удалить</p><input type="radio" value="page" name="delPage">Страницу <input type="radio" value="translate" name="delPage">Перевод';
    },

Get the scoop function of the source code found _setOption. It is the idea should be to establish such an option. But have not figured out how to use it. Can anyone experienced this?
