Help me to crack this...

in your controller, create an array to hold the values. each time you click the add button, it should add the new item to this array. Then you just use ng-repeat to iterate through the array. — Claies

I would actually build a directive for that...jsfiddle.net/ftfish/KyEr3 — Jony-Y

may use directive. In directive, bind click event, and operate DOM like using jQuery. — user4898717

@Subho directives are the best way to solve the problem if the dom maniputlation is not based on data. As you said you are a beginner this tutorial will help you understand the directives in a simple way weblogs.asp.net/dwahlin/… — Kashif Imran

You can use an Angular directive and jquery selectors. Basically replace the button with a directive that emits a button attached to a click event. On the click event clone the div html, compile it using $compile service in angular and append it to the body. see example

var app = angular.module('addDivApp', []);

app.controller('addDivController', function($scope) {

});

app.directive('addDivDirective', function() {
  return {
    restrict: 'A',
    scope: true,
    template: '<button id="addDiv" class="btn btn-default" ng-click="click()">Add</button>',
    controller: function($scope, $element, $compile) {
      $scope.clicked = 0;
      $scope.click = function() {
        $('body').append($compile($('.form-group').clone())($scope));
      }
    }
  }
});

<!DOCTYPE html>
<html ng-app="addDivApp">

<head>
  <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>

Add below code in your controller and do a little change in html. Add ng-repeat in div tag to repeat and ng-click method in button to call functions.

$scope.divCount=[{}];
$scope.addDiv=function(){
    $scope.divCount.push({});
};

$scope.removeDiv=function(){
    $scope.divCount.splice($scope.divCount.length-1,1);
}

 
<div class="form-group row" ng-repeat="count in divCount">      
            <label class="col-md-1 control-label">IF</label>
            <div class="col-md-2">
                <select name="TableName_1" size="0" style="width: 100%;">
                    <option value="Table_1">Table 1</option>
                    <option value="Table_2">Table 2</option>
                    <option value="Table_3">Table 3</option>
                    <option value="Table_4">Table 4</option>
                    <option value="Table_5">Table 5</option>
