Thank you Alexandre Follin for your quick response.
Please correct my code if am going wrong
Here is my code for directives (js/directives/programListing.js):
restrict : 'A',
templateUrl : 'js/directives/programListing.html'
and as you suggested I move the code .content to js/directives/programListing.html.
Here i could not understand how to use listing attribute in view.
