    copied!<p>I am trying to create a simple paginator directive. The idea is that i have a dynamic table based on a category. Eg: Category-> Fruits, table will have Apple, Bananas, Oranges etc Category -> Vegetables, table will have Spinach, Cauliflower and so on</p> <p>I am trying to build a dynamic paginator directive</p> <p>The code is below</p> <pre><code>myApp.directive("myPaginator",function(){ return { restrict:"AE", replace:true, scope:{ displayPage :"=", numPages : "=" }, link:function(scope, element, attrs, ctrl){ scope.$watch(scope.numPages, function(){ console.log("New num pages:"+scope.numPages); scope.nPages = parseInt(scope.numPages,10); scope.pages=[]; for (var i=0;i&lt;scope.nPages;i++) { scope.pages.push({value:''+(i+1),text:'Page '+(i+1)}); } }, true); console.log("Watch is bound"); }, controller:function($scope){ $scope.onPrevClick=function(newIndex){ $scope.displayPage = $scope.displayPage -1; } $scope.onNextClick=function(newIndex){ $scope.displayPage = $scope.displayPage +1; } $scope.onFirstClick=function(newIndex){ $scope.displayPage = 1; } $scope.onPrevClick=function(newIndex){ $scope.displayPage = $scope.numPages; } }, template:"&lt;div style='clear:both' class='pagination'&gt;&lt;ul &gt;"+ "&lt;li&gt; &lt;a ng-click=\"\"&gt;First&lt;/a&gt;&lt;/li&gt;"+ "&lt;li &gt;&lt;a ng-click=\"\"&gt;Previous&lt;/a&gt;&lt;/li&gt;"+ "&lt;li &gt;&lt;a ng-click=\"\"&gt;Page :&lt;select ng-model='displayPage' "+ " ng-options='option.value as option.text for option in pages' ng-change=\"gotoPage()\"&gt;"+ "&lt;/select&gt;&lt;/a&gt;&lt;/li&gt;"+ "&lt;li &gt;&lt;a ng-click=\"\"&gt;Next&lt;/a&gt;&lt;/li&gt;"+ "&lt;li &gt;&lt;a ng-click=\"\"&gt;Last&lt;/a&gt;&lt;/li&gt;"+ "&lt;/ul&gt;&lt;/div&gt;" }; }) </code></pre> <p>usage</p> <pre><code>&lt;div my-paginator num-pages='numPages' display-page='currPage'&gt;&lt;/div&gt; </code></pre> <p>The numPages get changed every time user picks a new category. The problem I am facing is the $watch on the numPages is never invoked even if the value is changed in the table</p>
