Как добавить data атрибут в массиве?

var tenant_fields = []; 
tenant_fields[0]=['Pudge', '<a class="kuda" href="" data-html="true" data-trigger="hover" data-toggle="popover"><img src="/images/heroes_small/pudge_small.png" style="width: 26px; height: 15px; margin-top: 0; margin-right: 4px" alt=""></a>']; 
 
var div = $("<div></div>"); 
div.html(tenant_fields[0][1]).find("a").attr("data-content", "test"); 
tenant_fields[0][1] = div.html(); 
 
console.log(tenant_fields[0]);
