Angular model not injecting rest call when trying to UPDATE - angularjs

Question

So basically I am very new to angular and node so go easy on me. I have been building a REST API for a profile site and it obviously requires updating of posts. I have GET, DELETE and CREATE working but stuck with trying to get the current post object (from stateParams) to inject into the editor.
// Uses sateParams to get object id
.controller('EditPostCtrl', ['$scope', 'Post',
'$stateParams', '$state', function($scope, Post,
$stateParams, $state) {
$scope.action = 'Edit';
$scope.isDisabled = true;
$scope.post = Post.findById({ id: $stateParams.id })
.$promise
}])
<h1>Post Editor</h1>
<form name="form" ng-submit="submitForm()">
<div class="form-group">
<!-- If Error -->
<!-- Blog Title -->
<label>Title:</label>
<input type="text" class="form-control" placeholder="Example Title" autocomplete="off" required ng-model="post.title"></input>
<br />
<!--
<label>Author:</label>
<input type="text" class="form-control" autocomplete="off" placeholder="{{ author }}" required ng-model="post.author"></input>
<br />
-->
<!-- Date -->
<label>Date:</label>
<input type="date" class="form-control" required ng-model="post.date"></input>
<br />
<!-- Post Content -->
<label>Blog content:</label>
<div ng-controller="editorCtrl">
<textarea type="text" class="ck-editor" autocomplete="off" required ng-model="post.content"></textarea>
</div>
<div class="pull-right buttonspacer">
Cancel
<button class="btn btn-default btn-lg">{{ action }}</button>
</div>
</div>
</form>

Answer 1

.controller("EditPostCtrl", function($scope,$http){
$scope.submitForm = function(id) {
$http.post('/api/postid/' + id)
.success(function(data) {
$scope.action = 'Edit';
$scope.isDisabled = true;
console.log(data);
})
.error(function(data) {
console.log('Error: ' + data);
});
};
});
in your angularjs,
you can use ng-click e.g.
<button class="btn btn-default btn-lg" ng-click="submitForm(post._id)">{{ action }}</button>
can you try this
