the important thing is to take the code from the enter button and then create the new line inside the array
$scope.addline = function ($event) {
    debugger
    if (event.keyCode == 13) {
        var algo = {};
        for (i = 0; i < $scope.etc.Fields.length; i++) {
            algo["seu array"] = ""
        }
        $scope.myArrayData.push(algo);
    }
}

the two keyboard enter keys have the same id ne?
