Angularjs OrderBy on ng-repeat doesn't work

$scope.teams isn't an array (it's an object of objects), and the orderBy filter only works with arrays. If you make $scope.teams an array, it will work:

$scope.teams = [    {      id: 100,      name: "team1",      count_win: 3,      count_loose: 2,      goal_average: 2,    },    {      id: 200,      name: "team2",      count_win: 3,      count_loose: 2,      goal_average: 1,    },            {      id: 300,      name: "team3",      count_win: 1,      count_loose: 2,      goal_average: 1,     }];

Or, you can add a special filter that works on objects, like this (borrowed from here):

app.filter('orderObjectBy', function() {  return function(items, field, reverse) {    var filtered = [];    angular.forEach(items, function(item) {      filtered.push(item);    });    filtered.sort(function (a, b) {      return (a[field] > b[field] ? 1 : -1);    });    if(reverse) filtered.reverse();    return filtered;  };});

And use it like this:

<tr ng-repeat="team in teams | orderObjectBy:order_item:order_reverse">

Note that this custom filter will not work with an array of sort orders as in the second part of your question.

You don't have to create a scope parameter for your orderBy, you can directly do this in your markup if you are dealing with arrays.

<tr ng-repeat="team in teams | orderBy:count_win:false">

With two parameters, you should just do

<tr ng-repeat="team in teams | orderBy:['count_win','goal_average']">

After for a more complex order, you could create a function in your scope like so :

$scope.customOrder = function (team) {    //custom}

And just call it like

<tr ng-repeat="team in teams | orderBy:customOrder">

Like @Jerrad said, ng-repeat only works with arrays, so you need to convert your teams object into an array to get it work properly.

ng-repeat works only on arrays, not on JSON objects.This was already discussed here: Angular - Can't make ng-repeat orderBy work

You either have to change the JSON object to an Array, or to convert it on the fly.The controller could then look like this:

var app = angular.module('app', []);app.controller('Ctrl', function ($scope) {    $scope.teams = [        {            id: 100,            name: "A Team",            count_win: 1,            count_loose: 2,            goal_average: 1        },        {            id: 200,            name: "C Team",            count_win: 2,            count_loose: 3,            goal_average: 4        },        {            id: 300,            name: "B Team",            count_win: 4,            count_loose: 1,            goal_average: 8        }    ];    $scope.predicate = 'name';});

I created a fiddle here with a demo containing your data:
