how change controlwrapper category filter ui.caption text color based on caption? tried following code,but not works.

var category_picker = new google.visualization.controlwrapper({                           'controltype': 'categoryfilter',                           'view': {'columns': [1,2,3,4,7,8]},                           'containerid': 'category_filter_container',                           'options': {                             'filtercolumnlabel': 'p/a',                             'ui': {                               'matchtype':'any',                               'label': '',                               'caption':'all',                               'labelstacking': 'horizontal',                               'allowtyping': false,                               'allowmultiple': false,                               'cssclass':'category_picker_class'                             }                           },                           'state':{'selectedvalues':['a']}                       });  var table = new google.visualization.chartwrapper({                                   'charttype': 'table',                                   'containerid': 'summary_details_table',                                   'options': {'allowhtml': true,'alternatingrowstyle':true,'width':'100%','height':'600px'}                               });  // create dashboard. var data_dashboard = new google.visualization.dashboard(document.getelementbyid('summary_details_table')).bind(category_picker, table).draw(view);  $(".category_picker_class").css({"color":"red"});

try wrapping jquery inside "ready" event handler control, control doesn't exist @ time try set css:

google.visualization.events.addlistener(category_picker, 'ready', function () {     $(".category_picker_class .charts-menu-button-caption").css({"color":"red"}); });

place event handler in between creating categorypicker , drawing dashboard. jsfiddle example
