Trying to set templateUrl to a dynamic URL

ionic-v1
5

@Dave - I am trying something similar but not having any luck:

templateUrl: function($stateParams) {
   return 'templates/'+$stateParams.url ;
}

even:

templateUrl: ['$stateParams',function($stateParams) {
  console.log("Menu :"+$stateParams.url) ;
  return 'templates/'+ $stateParams.url ;
}],

You can see more details in my thread here: How to dynamically pass parameter to ionic tabs templateUrl?
