Change text after loading html part?

Question

JavaScript

The bottom line is that you need to rename the menu item from "Item1" to "Item2".
But "Point1" appears only when you move the mouse over "button1" (and it will appear for about 1-2s). Moreover, it is generated on the fly (there is no hidden element).

The essence of the algorithm is as follows:
1.Hover the cursor over "button1" 2.After 1-2s, "Point1"
appears
3.When "Point1" appears, we catch this event and $('#punkt1').html(Point2).
Is there an event that will catch the readiness of the element (item 2 in the algorithm) to work with it.
