Jquery Dom Refresh

Hello there. I use drag and drop to add html elements to the page, and I give each element an id. And I write the knowledge of that element once about which element I come to with the mouse. I noticed one thing but I created a blank page and added elements successfully added successfully. When I put the mouse on it, it does not get the id knowledge. But if you save the page and keep repeating it, it writes the id information about the element you're typing with the mouse. When I add something new, the event that I am going to repeat happens again, the newly added elements display the ID information until the page is saved and reopened. I do not know what it's called.
