Dynamically setting new ng-model when pushing model to array - angularjs

Question

Can't figure out how to dynamically add a new model whenever a new row is added to the page. For example, the input select box ng-model= infos.rigBonusInfo.rigName is used for all select box I've added to the page. I would like to have a different model attached to a each select inputs. I tried using ng-model= infos.rigBonusInfo.rigName[rigBonus] but it doesn't work for the rates as the same model gets attachedto each rate field.
Pretty much what I want to do is to bind a new model whenever a new row gets pushed into the array.
Currently, I have a nested table which is the following:
<div class="col-lg-5">
<table class="table table-striped table-bordered">
<thead>
<tr>
<th>Rig</th>
<th>Rig Name</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="rig in rigs">
<td>{{ $index + 1 }}</td>
<td>{{ rig.name }}</td>
</tr>
</tbody>
</table>
</div>
<div class="col-lg-2"></div>
<div class="col-lg-5">
<table class="table table-striped table-bordered">
<thead>
<tr>
<th>Bonus Name</th>
<th>Rate</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="bonus in create.rigBonusRates">
<td>{{ bonus.rateName }}</td>
<td>{{ bonus.rate }}</td>
</tr>
</tbody>
</table>
</div>
<table>
<thead>
<tr>
<th>Date</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="rigDate in rigDateList track by $index">
<td><input ui-date="datepickerOptions" ng-model="date" /></td>
<td>
<table>
<thead>
<tr>
<th>Rig</th>
<th>Rate1</th>
<th></th>
<th>Rate2</th>
<th></th>
<th>Rate3</th>
<th></th>
<th>Rate4</th>
<th></th>
<th>Comments</th>
</tr>
</thead>
<tr ng-repeat="rigBonus in rigBonusList track by $index">
<td><select ng-options="rig as rigs.indexOf(rig) + 1 for rig in rigs" ng-model="infos.rigBonusInfo.rigName[rigBonus]" ></select></td>
#for (var i = 1; i < 5; i++)
{
<td><select ng-options="rigBonus.rateName for rigBonus in create.rigBonusRates" ng-model="infos.rigBonusInfo.rate#(#i)"></select></td>
<td><input type="text" ng-disabled="infos.rigBonusInfo.rate#(#i).rateName != 'Special' " ng-model=infos.rigBonusInfo.rate#(#i).rate /></td>
}
<td><input ng-model="info.rigBonusInfo.comments" /></td>
</tr>
</table>
</td>
</tr>
</tbody>
</table>
<div>
<button type="button" ng-click="add()">Add</button>
<button type="button" ng-click="addDate()">Add Date</button>
</div>
My current controller has the following:
angular.module('RigBonus').controller('rigCreateController', ['$scope', '$http', 'PayPeriodService', 'RigLegendService',
function ($scope, $http, PayPeriodService, RigLegendService, RigBonusRateService) {
$scope.rigs = RigLegendService.getRigLegend();
$scope.datepickerOptions = {
orientation: 'top',
startDate: PayPeriodService.getStartDate(),
endDate: PayPeriodService.getEndDate()
};
$http({ method: 'GET', url: '/Home/CreateData' }).success(function (data) {
$scope.create = data;
$scope.infos = {
rigBonusInfo: {
rigName: $scope.rigs[0],
rate1: $scope.create.rigBonusRates[0],
rate2: $scope.create.rigBonusRates[0],
rate3: $scope.create.rigBonusRates[0],
rate4: $scope.create.rigBonusRates[0],
comment: ""
}
};
$scope.add = function () {
$scope.rigBonusList.push();
};
$scope.addDate = function(){
$scope.rigDateList.push("");
};
});
$scope.rigBonusList = [$scope.rigBonusInfo];
$scope.rigDateList = [];
$scope.submit = function () {
$http.post('/Home/Create', {model: "testing"} );
};
}]);

I figured out my issue. My problem was that I was not sure how to generate a new object when a new row of controls are added. Think I should have put something on fiddleJS to help people visualize it better. As a static model was used ($scope.infos) as ng-model, the same model was used for two different controls which I don't want. I want all my controls to be unique.
The fix was to create the object I had in mind which is the following:
$scope.rigDateList = [{
date: "",
rigBonusList: [{}]
}];
So it is an array of objects where the object contains a date and another array of objects.
When I want to push new objects to the inside array which I didn't know I could just create objects like this at the time. I was trying to figure out a way to dynamically create new models ng-model could by declaring them in the controller. I use the following function:
$scope.rigDateList[$scope.rigListIndex].rigBonusList.push({
rigName: "",
rate1: "",
rate2: "",
rate3: "",
comments: ""
});
I also didn't know that I could use elements inside the array from ng-repeat. In the following case, it is rigBonus that I could have used as a model instead of infos model.
<tr ng-repeat="rigBonus in rigDate.rigBonusList track by $index">
<td><select ng-options="rig as rigs.indexOf(rig) + 1 for rig in rigs" ng-model="rigBonus.rigName"></select></td>
and when I want to push to the outside array I use the following:
$scope.rigDateList.push({
date: "",
rigBonusList: [""]
});
$scope.rigListIndex = $scope.rigListIndex + 1;
I use an index to keep track of which object I'm in.

A more closest question and answer is that:
