How to properly declare a regular expression?

Question

JavaScript

Here is the working code:

var regul = /(AAA|BBB|CCC|DDD)\(.*?\)/g;
var str = "one two 12AAA(CCC(C1_1);A1_1)dfg dfgdfgdfg,BBB(B1_1; B1_2) sfsgndf dfgnhjdfglkjdfg DDD(D1_1)";
var ARR = str.match( regul );

for(var i = 0; i < ARR.length; i++) {
    console.log((i+1)+') '+ARR[i]);
}

But this code works if there are no other functions in the brackets ....
But if there is another function in the function, the script does not work correctly ..
It outputs the following:
1) AAA(CCC(C1_1)
2) BBB(B1_1; B1_2 )
3) DDD(D1_1)
Although, I would like to see:
1) AAA(CCC(C1_1);A1_1)
2) CCC(C1_1)
3) BBB(B1_1; B1_2)
4) DDD(D1_1) Tell me
how to fix it so that worked...
