Added elements not responding to mouseenter?

Question

JavaScript

In table 1, the line is set when loading, and I add the second through append.
There are elements in the line (for example, a picture with a basket). The JS file contains the code
$(.del_ico).mouseenter(function() { действия });
. On hover, the image changes.
The mouseenter event does not fire on the newly added row.
My guess is that the script $(.del_ico).mouseenter(function() { actions }); does not see newly added elements or am I stupid somewhere?

Of course he doesn't. Google for "javascript event delegation".
Or just read the textbook .
