Do searchers interpret the elements before or after rendered by Javascript?

Question

For example, in a ng-repeatangular or in single append of Jquery, searchers will read all elements created dynamically, since it is a replace client-side?

In the section below, taking the example of Jquery, I have a div.blockquote which will be replaced by a real tag <blockquote> as well as its content that, as it is in a predefined format, will be divided into several tags so that the semantics is preserved. Searchers will take this new tag and their "daughters into consideration"?

(function blockquote(){
	$('.blockquote').each(function(i){
  	var self = $(this);
    var phrase = self.html().split(/---/)[0].replace(/\n/g, '<br>');
    var footer = self.html().split(/---/)[1];
    var autor  = footer.split('#')[0];
    var autorHref = footer.split('#')[1];
    var blockquote = $('<blockquote></blockquote>');
    var text = $('<p></p>');
    var line = $('<hr>');
    var footer = $('<footer></footer>');
    var cite = $('<cite></cite>');
    blockquote.insertAfter(self);
    text.appendTo(blockquote).html(phrase);
    line.appendTo(blockquote);
    footer.appendTo(blockquote).html(' - ');
    cite.appendTo(footer).html('<a href="'+autorHref+'" target="_blank">'+autor+'</a>');
    blockquote.find('br:last, br:first').remove();
    blockquote.children('p').prepend('<br>');
    self.remove();
  })
})();
