The wierd issue here is that stuff that I put on the scope within the success - doesn't work. - actually nothing in the update function persists in scope. I see that the request is fine because I see the console.log at line 36. The controller is defined in index.html that ng-includes profile.html For instance the $scope.authenticated is not set …

dashboard.js

function DashboardController($scope, $http, $location) {
$scope.list = ['ש.עבודה','משימות','הודעות','מערכת','מבחנים'];
$scope.test = ['1','2','3','4'];
$scope.dis='none';

    $scope.start=function () {
  	console.log("hello");
	}
	 $scope.show=function (item) {
		if (item=='מערכת') {
			$scope.timetable=['ראשון','שני','שלישי','רביעי','חמישי','שישי'];
		}
		else {
			$scope.timetable=null;
		}
		$scope.item=item;
	}
	$scope.doBig = function(i){
		/*alert(i);*/
		$scope.side=i;
		$scope.dis='block';
	}

	$scope.master= {};

  	$scope.update = function(userpass) {
  		console.log(userpass);

    //$scope.master= angular.copy(user);
    $http.post("/0.1/login",userpass)
    	.success(function(data, status, headers, config) {  
	        $scope.user.password = null;
	    	if (data.success) {
	         	console.log(data.user);
	    	 	$scope.user = data.user;  		
	    	 	$scope.authenticated = 'zebra';
	         	$scope.err = false;
	         	$location.path("/dashboard");
	    	} else {
	    	  	$scope.err = data.errDesc;
	          	$scope.authenticated = false;    			
	    	}
	    	$scope.$apply();
		}).error(function(data, status, headers, config) {
        	$scope.user.password = null;
    		$scope.status = status;
		});
		
  	}
  }

Lior, Add $scope.$apply() at the end of the success callback. That should update the scope

I did but now I get $digest is in allready in progress errors.

if you use Angular's providers (i.e $http) you should probably not use $apply.
And usually its best (practice) to not use the $http provider from the controller, but from a service/factory
Please put it on JsFiddle or jsBin

Lior, i would put the response data parameter inside - $scope.responseData
and watch it with - $scope.$watch

the watch third parameter should be true btw. (if its an object properties that are changed..)
