Answer 1

setTimeout takes two(or more) arguments. First one is a callback function that will be called after X miliseconds. X is the second argument.
setTimeout first waits for all pending tasks. Then waits X milliseconds and calls the callback function.
In my code I used setTimeout (function,0) to wait for the paste event fulfillment. This way i cleared the input value 0 milliseconds(a bit more but as soon as js could) AFTER the value was pasted and updated.

Answer 2

Because myFunction gets called just before the input value is updated.
