angular bind scope data to templateCache

I have this function in my controller, which loads in a template

$http.get('scripts/routes/template.html', { cache : $templateCache})
    .then(function(val){
        var returnedTemplate = val.data; // returns string
        $scope.name = 'blah blah';
        $scope.message = 'Good day';
    });

The template that that it loaded in by val.data, is a string 

<h3 class="md-title">{{name}}</h3>
<p class="md-title">{{message}}</p>

How do I get the string that is returned from the loaded template and bind the scope vars to the string?

The result I need is 

<h3 class="md-title">blah blah</h3>
<p class="md-title">Good day</p>

I have tried to use the $compile functions to bind the data to the string but to no avail.

Thanks in advance for the help

Thank you, you pointed me in the right direction, this is the solution that works best for my set up. 

angular.module("app",[])
.controller("ctrl",function($scope, $compile, $timeout){
        $scope.name = 'blah blah';
        $scope.message = 'Good day';
        var returnedTemplate = '<div><h3 class="md-title">{{name}}</h3><p class="md-title">{{message}}</p></div>';
        var element = $compile(returnedTemplate)($scope);

        $timeout(function() {
            var confirmDialogMessage = element.html(); // needed time
            console.log(confirmDialogMessage); // here I got the html with values in, but still in a string

       }, 300);
        
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl"></div>

you need to manually compile the html after the binding. create a directive like this.

.directive('dynamic', function ($compile) {
  return {
    restrict: 'A',
    replace: true,
    link: function (scope, ele, attrs) {
      scope.$watch(attrs.dynamic, function(html) {
        ele.html(html);
        $compile(ele.contents())(scope);
      });
    }
  };
});

then call this in the html and bind the html string to directive 

<div dynamic="returnedTemplate"></div>

Controller

$scope.name = 'blah blah';
 $scope.message = 'Good day';
 $scope.returnedTemplate = '<h3 class="md-title">{{name}}</h3><p class="md-title">{{message}}</p>'

Demo

angular.module("app",[])
.controller("ctrl",function($scope){

        $scope.name = 'blah blah';
        $scope.message = 'Good day';
 $scope.returnedTemplate = '<h3 class="md-title">{{name}}</h3><p class="md-title">{{message}}</p>'
}).directive('dynamic', function ($compile) {
  return {
    restrict: 'A',
    replace: true,
    link: function (scope, ele, attrs) {
      scope.$watch(attrs.dynamic, function(html) {
        ele.html(html);
        $compile(ele.contents())(scope);
      });
    }
  };
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
 <div dynamic="returnedTemplate"></div>
</div>
