All Bougies bloom at the tips of this season's growth. Since they are vines, they don't normally have a lot of ends of canes. In fact, they would be perfectly happy to have only one or two bull canes that grow like mad covering a lot of distance with a thick stem. That doesn't suit our fancy in a pot, so we clip the canes when they get too long by our standards. The normal growth pattern is for one leader to begin to extend. If allowed to grow normally it will extend until it is some length, and then leaders develop along that cane and begin to extend, too. At about the same time another leader somewhere else goes next, ad infinitum. The length of the stem is more a function of time than length attained. Outdoors in perfect conditions that length could be ten or twenty feet. Indoors in so-so conditions that could be ten or twenty inches. To get a lot of short canes you need to clip every canes when the single leader extends to an internode length that is unacceptable to you. For me that's more than an inch. By leader, I mean the single leaf at the end of the stem. The distance between it and the second leaf is the internode length. Eventually the plant gets the message and many leaders all over the place extend simultaneously more like a bush than a vine, all with tight clusters of foliage instead of in the form of a stem with the leaves inches apart along the stem. None of the tips that you have cut off in this process will bloom, but you won't notice them.
