Make a dash system using the Character Controller of Unity

Hello there ! I'm trying to make a Top Down Shooter game with a dodge/dash/roll system. But the problem is here, I'm using the Character Controller from Unity for move my character and I think this is the problem why my character is not able to go to another position after pressing the input. The character just stand on place even if I control the dash movement with the animation itself ( in this case, the animation make the player move but at the end he go back to his last position ). I hope my english was not that bad and you can understand my problem ^^'
