click and clickLabel function no working by CasperJS -

i try data website http://www.bestbuy.com/site/dji-phantom-3-standard-quadcopter-white/4406800.p?skuid=4406800 using casperjs.

my situation have click button ratings & reviews data show out.

but check out screen shot this.capture('check2.png); after this.click('#reviews-accordion.accordion-wrapper'); looks button never been clicked , cause can't data rating , date

i have try selector , still doesn't work.

casper.then(function () {     this.click('.accordion-toggle.accordion-item');     console.log('clicked reviews tab'); });  casper.then(function() {     this.clicklabel('ratings & reviews', 'button');     console.log('clicked clicklabel'); });
