javascript - Updating Columns Dynamically - Alloy UI -


i'm trying change columns dynamically in alloy ui datatable - depending on button selected, columns changed depending on data returned.

my columns updated, actual data never included in table. when don't define columns both columns , data returned - of course want control of how columns displayed , want set attributes

below code:

 var datatable = new y.datatable({ //defining datatable no columns preset     editevent: 'dblclick',     plugins: [{         cfg: {             highlightrange: false     }] });  button.on(     'click', //on click...     function() {         var category = $(this).attr("id"); //value retrieved id of button selected          datasource = new y.datasource.io({source: '/searchmydata         datasource.sendrequest({             datatype: 'json',             on: {                 success: function(e) {                     response = e.data.responsetext;                     setcolumnnames(category); //set columns...                     data = y.json.parse(response);                     datatable.set('data', data);//then data                     datatable.render('#my-container');                 },                 failure: function() {                     alert(e.error.message);                 }             }        });  function setcolumnnames(tabname){ //defining columns     var columns1 = [         { key: 'id', label: 'id', width: '70px' },         { key: 'name', label: 'name', width: '70px' }       ];      var columns2 = [         { key: 'id', label: 'id', width: '70px' },         { key: 'addr', label: 'address', width: '70px' }       ];      switch (category) {          case "person":             datatable.set('columns', columns1);             break;         case "address":             datatable.set('columns', columns2);              break;         default:              console.log(''); }

there's no issue data returning ajax request, when comes loading table new set of columns defined. i've tried reset() method on both columns , data on each click, no luck.

it turns out keys returned request being capitalized , included underscores (just how they're defined in database) - i've noticed defining columns key case sensitive. if changed single character lower case upper column not display data.
