Adding data attribute to DOM

$('div').data('info', 1);

alert($('div').data('info'));
//this works    

$('div[data-info="1"]').text('222');
//but this don't work

I’m creating element within jquery. After that, I want to add attribute “data”. He’s like and is added, but in the DOM, this is not apparent, and I can’t get the item, using

$('div[data-example="example"]').html()
