JS Error with Angular JS Module

I wrote a Module to keep track of all my helper functions (scripts/apps.js):

angular.module('app', ['ngResource']).run(function($scope){

$scope.UTIL = {

setup_pod_variables: function (pods){...}
...

});

I'm trying to call the helper function from my Controller defined in another directory: scripts/controller/Dashboard.js:

scope.UTIL.setup_pod_variables(pods);

I have included the other module:

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

But it seems that I am still getting an error:

TypeError: Cannot read property 'setup_pod_variables' of undefined
