Dynamic ui-sref in directive template Angular Js - html

Question

In my angular js Application, I have a directive inside a ng-repeat. Directive has a template in which the HTML part is loaded. Inside that template I am declaring a ui-sref Router dynamically setting states!
This does not Work!
I have tried a Fiddle
Without using a Directive ui-sref works Fine. But I need it in Directive's template.
MY HTML PART
<div ng-repeat="sp in obj.PEs">
<div draw-pe proc="{{sp.peId}}"></div>
</div>
<div style="border:1px;" ui-view="properties"></div>
My Script Part
var myApp = angular.module('myApp', ["ui.router"]);
myApp.controller("testCtrl", function($scope) {
$scope.obj = {
"PEs": {
"1": {
"peId": "1",
"peName": "Exp1",
"peDisplayName": "Exp",
"peType": "Exp",
"peCategory": "PE"
},
"2": {
"peId": "2",
"peName": "RN1",
"peDisplayName": "RNull",
"peType": "RN",
"peCategory": "PE"
}
}
}
})
myApp.config(function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/');
$stateProvider
.state('Exp', {
url: '/Exp/:peId',
views: {
"properties": {
template: ".<h3>I am Exp ! </h3>",
controller: function($scope, $stateParams) {
var peId = $stateParams.peId;
alert("Peid-> " + angular.toJson($scope.obj.PEs[peId]));
}
}
}
})
.state('RN', {
url: '/RN/:peId',
views: {
"properties": {
template: "<h3> I am RN ! </h3>",
controller: function($scope, $stateParams) {
var peId = $stateParams.peId;
alert("Peid-> " + angular.toJson($scope.obj.PEs[peId]));
}
}
}
})
});
myApp.directive("drawPe", function() {
return {
restrict: "AE",
template: '<div ui-sref="{{peObj.peType}}( { peId:peObj.peId } )"> <h5>{{peObj.peDisplayName}}</h5></div>',
link: function($scope, element, attrs) {
var procId = $scope.$eval(attrs.proc);
alert(procId);
// alert(angular.toJson(scope.obj.processElements[procId]))
$scope.peObj = $scope.obj.PEs[procId];
}
}
})
See the Browser Console, on clicking the output Part!
ERROR
Error: Invalid state ref '( { peId:peObj.peId } )'
What will be the best Practice to call dynamic state names inside directives Template? I Have read some previous asked question and answer, But I am not clear with the idea as I am new to Angular Js.
Any Idea/help appreciated
Thanks

You can use $compile service to compile your directive's template when your scope changes.
Your directive could look like this:
myApp.directive("drawPe", function($compile) {
return {
restrict: "AE",
tranclude: true,
scope: {
peObj: '='
},
template: ' <h5>{{peObj.peDisplayName}}</h5>',
link: function(scope, element, attrs) {
console.log(scope.peObj);
scope.$watch(
function(scope) {
// watch the 'compile' expression for changes
//return scope.$eval(attrs.compile);
},
function(value) {
$compile(element.contents())(scope);
}
);
}
}
});
And your html:
<div ng-repeat="sp in obj.PEs">
<div draw-pe pe-obj="sp" proc="{{sp.peId}}"></div>
</div>
<div style="border:1px;" ui-view="properties"></div>
