While Right Click, options comes in the left side

I was worked on to make the right click as my customize menu to display using the mouse by using the below code:

click: function (event) {
    var eventResult = this.get('tableView').clickRow(event, this.get('object'));
    if (eventResult !== false) {
        this.get('element').focus();
        $('.content-row').bind('contextmenu', function(e) {
            e.preventDefault();
            var parentId = $(this).closest('tr').prop('id');
            $('#'+parentId).find( ".managed-object-action-menu" ).click();
        });
    }
    return eventResult;
},

But What happen means the options are coming in the left side for right click options. I need the options come by on right side for right click on mouse. I'm new to the ember. Your help will be appreciate. Thanks in advance.
