Ruling on a double "T"

[xxssmen]

(Rec. league) A1 is ready to attempt 2 free throws, before I toss A1 the ball A2 and B1 is trash talking and I have warn both players earlier about trash talking, before I toss the ball to A1 both A2 and B1 kept jawing at each other I finally had enough so I called a double Technical on A2 and B1.
What is the ruling here?

I’m not sure if I did this right or not, I reported the double technical and went with the alternating possession which was for team A since there was no team control at the time I called a Double “T”. Anyway I cleared the lane and allow A1 to shoot his free throws and gave the ball back to team “A” at the baseline for a spot throw in.

Now that I had time to look back on the call I made I realized I should of not given the free throws attempt to A1 and should of went with the alternating possession which was team “A” possession at the division line.

I cannot seem to find the ruling in the book for this scenario any help would be appreciated.
