How can we add a textbox element to a form dynamically using AngularJs. For example in this case, I have a text and textbox which I want to add one other of this pair by clicking on a button using AngularJs.
<div ng-app>
<div ng-controller="ClickToEditCtrl">
<div ng-hide="editorEnabled" ng-click="editorEnabled=true">
{{title}}
</div>
<div ng-show="editorEnabled">
<input ng-model="title">
<button href="#" ng-click="editorEnabled=false">Done editing</button>
</div>
</div>
</div>
<div>
<input type="text" placeholder="Enter answer">
</div>

Steps to Create Dynamic Forms AngularJS: Create an empty array in your controller. Create the input fields inside the section tag with the ng-repeat directive to loop over the array. Set ng-model dynamically. Create two methods in $scope object to add and remove input fields.
The $ in AngularJs is a built-in object.It contains application data and methods.
An AngularJS form can be submitted using either ng-submit or ng-click directive but not both. Ng-submit: Binds angular expression to onsubmit event when form does not include action attribute. Ng-click: Binds angular expression to onclick event.
I implemented it myself. You could dynamically add an element by using ng-repeat in a
<li ng-repeat="elemnt in questionelemnt">
Here it is the Demo: fiddle

js file
$scope.choices = [{id: 'choice1'}, {id: 'choice2'}, {id: 'choice3'}];
$scope.addNewChoice = function() {
var newItemNo = $scope.choices.length+1;
$scope.choices.push({'id':'choice' +newItemNo});
};
$scope.showAddChoice = function(choice) {
return choice.id === $scope.choices[$scope.choices.length-1].id;
};

<div class="form-group" data-ng-repeat="choice in choices">
<label for="choice" ng-show="showChoiceLabel(choice)">Choices</label>
<button ng-show="showAddChoice(choice)" ng-click="addNewChoice()">Add another choice</button>
<input type="text" ng-model="choice.name" name="" placeholder="Enter a restaurant name">
