They will only draw wax when all drawn comb is being used. If the drawn boxes are not full, they will fill those cells first, before drawing any new comb.And
there is enough bees in the hive to occupy the space of the new frames. Bees always work underfoot, whether it is tending brood, processing nectar/pollen, or building comb. If there isn't enough bees to force the population into a new super it will just sit there until there is, even if all the available comb is full and capped.
It's important to keep the brood chamber open so the queen will have plenty of combs for laying new eggs. The larger the brood chamber the larger and faster the hive population will expand.
In a 10 frame hive the outside frames (1 & 10) are almost always storage combs, move those up into the super, move frames 2 & 8 into the 1 & 10 location a place new frames in the 2 & 8 location.
That keeps the Building combs in the brood chambers, provides new combs for the queen to lay in (expanding the population), and baits the honey super with honey combs.
See how it all fits together?
