[Star Wars] How did Yoda and Obi-Wan manage to retake the Jedi Temple after the Purge?

Also, if there were surviving Jedi's after Order 66, how come they didn't find the rest of them and try to rebuild the Order, They could of gone to some off-world planet and slowly rebuild it.

They didn't retake it, they broke in to the equivalent of the security officer room to look at the holographic records and change the signal calling the Jedi back to Corosount. 

They probably waited for a shift switch in the clone troops watching that part of the Jedi Temple and attacked them when there number where lowest, a quick in and out with minimum guards around hardly qualifies as taking back the entire Temple.
