2 bluetooth gamepad working as player 1

I just bought two of these joysticks: http://bit.ly/2bb41yD

Then I paired them with my retropie, configured the keys, but both are working as player 1, I tried all kind of configurations but no success =/

Here is my /opt/retropie/configs/all/retroarch.cfg

input_player1_joypad_index = 0
input_player1_a = 1
input_player1_b = 2
input_player1_y = 4
input_player1_x = 3
input_player1_start = 0
input_player1_select = 5
#input_player1_l = "q"
#input_player1_r = "w"
input_player1_left = "left"
input_player1_right = "right"
input_player1_up = "up"
input_player1_down = "down"
input_player2_joypad_index = 1
input_player2_a = 1
input_player2_b = 2
input_player2_y = 4
input_player2_x = 3
input_player2_start = 0
input_player2_select = 5
input_player2_left = "left"
input_player2_right = "right"
input_player2_up = "up"
input_player2_down = "down"`

I also have this configuration in /etc/udev/rules.d/10-local.rules

SUBSYSTEM=="input", ATTRS{name}=="MOCUTE-036_B50-AC10", MODE="0666", ENV{ID_INPUT_JOYSTICK}="0" 
SUBSYSTEM=="input", ATTRS{name}=="MOCUTE-036_B50-BB62", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1" 

while configuring in emulation station the input, it only was showing 1 gamepad detected keyboard, but after changing both to ENV{ID_INPUT_JOYSTICK}=“1” it says 2 gamepad detected, but when i go to some games, both players controls player 1 (but seems that start/pause is working correctly, since I can enter the second player in games like Goof Troop SNES.

SUBSYSTEM=="input", ATTRS{name}=="MOCUTE-036_B50-AC10", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1" 
SUBSYSTEM=="input", ATTRS{name}=="MOCUTE-036_B50-BB62", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1" 

Does anyone know for sure what does it mean ENV{ID_INPUT_JOYSTICK}=“1”? and the subsystem? maybe here I have to change to gamepad? I’m trying for one week already to make it work properly but get stuck in this part.

Can someone help me?
