my javascript jquery doesn't work in script but work in console

I have my javascript :

$(".highcharts-container .highcharts-data-labels g text").each(function(){
            console.log("au milieu");
            $(this).on('click',function(){
                console.log("test : "+$(this).html());
            });
        });

it is inside : $(document).ready(function() {

Every other javascript function work fine but not this one. The JS file is charged by the page.

Any ideas ?
