tableviewrow hasChild property usage

Hi I set the hasChild Property to true to a row of the table.I want to add options to the hasChild property.. Plz anyone tell me How to do that? Thanks in Advance

capture the click event on the table object and then build your user interfarce

table.addEventListener('click', function(e) {
    if (e.rowData.hasChild){
        //do whatever you need
    }
}

take a look to the KitchenSink table examples
