Javascript share a generic callback with unique states

I have a working but tedious code.

I have 6 of the onoff objects to describe 6 GPIO inputs. All of them need to register a callback [i.e. obj.watch(callback)] to detect state change.

Currently, my functional code looks like this

Var states = [[0,0], [0,0], [0,0]];
Var handle0 = function (err, A) {
    State[0][0] = A;
    Eval0(state[0]);
}
Var handle1 = function (err, A) {
    State[0][1] = A;
    Eval0(state[0]);
}
Var handle2 = function (err, A) {
    State[1][0] = A;
    Eval1(state[1]);
}
Var handle3 = function (err, A) {
    State[1][1] = A;
    Eval1(state[1]);
}
Var handle4 = function (err, A) {
    State[2][0] = A;
    Eval2(state[2]);
}
Var handle5 = function (err, A) {
    State[2][1] = A;
    Eval2(state[2]);
}
Input0.watch(handle0);
Input1.watch(handle1);
Input2.watch(handle2);
Input3.watch(handle3);
Input4.watch(handle4);
Input5.watch(handle5);

As you can see, the routines are mostly the same, but just need to access different variables. However, since the onoff.watch callback expect a function to handle two parameters (error status, and value), I don’t know how to extend my callback to make it generic to include my state information.

Are there a design pattern to simplify these callback creation?
