cursor moves to new generated textbox in angualarjs - angularjs

Question

I have form with modal, When i click enter or add email button it generates the new text box but cursor will not move into that text box.
But i need when i click enter or add email button, then cursor automatically should move to the newly generated text box.
My html code
<script type="text/ng-template" id="myModalContent">
<div class="modal-header">
<h3 class="modal-title">I'm a modal!</h3>
</div>
<div class="modal-body">
<li ng-repeat="item in items " ng-form="subForm">
<input type="text" name="name" ng-model="item.email" required ng-pattern="/^[_a-z0-9]+(\.[_a-z0-9]+)*#[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$/" ng-enter="addOrRemove($index,item.email)"/>
<span ng-show="subForm.name.$error.required" style="color: red">Email required</span>
<span ng-show="subForm.name.$invalid" ng-hide="subForm.name.$error.required" style="color: red">Invalid email</span>
<button ng-disabled="subForm.name.$invalid || subFform.name.$dirty" ng-click="addOrRemove($index,item.email)" >{{item.value}}</button>
expression: {{subForm.name.$invalid}}
</li>
</div>
<div class="modal-footer">
<button class="btn btn-primary" ng-click="ok()">OK</button>
<button class="btn btn-warning" ng-click="cancel()">Cancel</button>
</div>
</script>
My javascript code
$scope.addOrRemove = function(indexSelected,rcvEmail)
{//alert($rootScope.email1);
if(!rcvEmail)
{
return
}
console.log("just check email",rcvEmail);
console.log("length of the object",$scope.items.length);
event.preventDefault();
if($scope.items[indexSelected].state == 1)
{
//console.log($scope.items[indexSelected].state);
$scope.items[indexSelected].value = "Remove email";
$scope.items[indexSelected].state = "0";
$scope.items[indexSelected].email = rcvEmail;
$scope.items.push({value: "Add email", state: "1"});
}
else
{
//console.log($scope.items[indexSelected].state);
//$scope.items.push({value: "Remove email", state: "1"});
$scope.items.splice(indexSelected, 1);
}
};

In order to focus an input you have to create custom directive.
.directive('focus', function($timeout, $parse) {
return {
restrict: 'A',
link: function(scope, element, attrs) {
scope.$watch(attrs.focus, function(newValue, oldValue) {
if(newValue) {
element[0].focus();
}
});
element.bind("blur", function(e) {
$timeout(function() {
scope.$apply(attrs.focus + "=false");
}, 0);
});
element.bind("focus", function(e) {
$timeout(function() {
scope.$apply(attrs.focus + "=true");
}, 0);
})
}
}
})
And then you can use it in the input.
<input type="text" ng-init="inp_focus = true" focus="inp_focus" />
Please check this example.
