You can use list_branch_details along with its StockBranchDetailsModel store inside it for every rows. and whenever any change in data the you can save to particular position of that list named list_branch_details and while sending data

var data ={};
var branches=[];
var branch ={};

data["name"] = "Test Stocks";
data["unit"] = "1";

for(int i =0;i< list_branch_details.length; i++ ) {
    branch = {};
    branch["branch_id"] = list_branch_details.get(i).getBranchId();
    branch["kg"] = list_branch_details.get(i).getKg();
    branches.add(branch);
}

data["branches"] = branches;

and just encode it.

jsonEncode(data);
