Customize ECB menu of Sharepoint hosted add-in

Question

How could I hide some menu items from a ECB menu in a Sharepoint add-in, based on permissions? My Sharepoint application is Sharepoint hosted not provider hosted, so the javascript injection method wouldn't work.

Thanks

Your application will always run with the current users permissions. If a permission level on a item in your menu has a higher permission level than the current user the user won't be able to access it. — Kodz, Nov 14 '15 at 08:52
Thank you for your reply. Is it possible to use usergroups and javascript? I can't find a workaround .. — Rahma, Nov 14 '15 at 18:32
Sure its possible, the best way i'd say would be to check if the current user is a member of a group. — Kodz, Nov 14 '15 at 18:52

Function to check if user is member of specified group

function IsCurrentUserMemberOfGroup(groupName, OnComplete) {

        var currentContext = new SP.ClientContext.get_current();
        var currentWeb = currentContext.get_web();

        var currentUser = currentContext.get_web().get_currentUser();
        currentContext.load(currentUser);

        var allGroups = currentWeb.get_siteGroups();
        currentContext.load(allGroups);

        var group = allGroups.getByName(groupName);
        currentContext.load(group);

        var groupUsers = group.get_users();
        currentContext.load(groupUsers);

        currentContext.executeQueryAsync(OnSuccess,OnFailure);

        function OnSuccess(sender, args) {
            var userInGroup = false;
            var groupUserEnumerator = groupUsers.getEnumerator();
            while (groupUserEnumerator.moveNext()) {
                var groupUser = groupUserEnumerator.get_current();
                if (groupUser.get_id() == currentUser.get_id()) {
                    userInGroup = true;
                    break;
                }
            }  
            OnComplete(userInGroup);
        }

        function OnFailure(sender, args) {
            OnComplete(false);
        }    
}

usage

function IsCurrentUserHasContribPerms() 
{
  IsCurrentUserMemberOfGroup("Members", function (isCurrentUserInGroup) {
    if(isCurrentUserInGroup)
    {
        // The current user is in the [Members] group!
    }
  });

}
ExecuteOrDelayUntilScriptLoaded(IsCurrentUserHasContribPerms, 'SP.js');

thank you for your help. Finally I've got what I wanted to customize in my page. I've overriden the CreateMenuOption in core.js by creating another file (I've used Chrome to get the code). I've used the following js file too : https://spservices.codeplex.com/ in order to get the group of the connected user.
