Please refer the console while you run - http://jsfiddle.net/E9bU5/239/

$scope.changecolor = function() {
    return colorlist[($scope.j++)%colorlist.length]; //Returns a string, not an object.
};

From other SO posts, I understand that this error is thrown when the result is an object and different all the time. But in my case it is just string. Then also it is throwing the error. How to fix this?

just dont put counter variable on scope? use j instead of $scope.j? – YOU May 15 '16 at 13:10
@YOU - Ohk, that's fine. But that doesn't stop the Digest errors! – anand patil May 15 '16 at 13:17
ah, you shouldn't call function() inside angular expressions, it will run many times until changes stop. – YOU May 15 '16 at 13:20
what are you trying to achieve? different colors for each numbers? – YOU May 15 '16 at 13:21
@YOU - Yes, diff color for each number. 2 Questions then. Other than function inside the expression, what else? Second, it's returning a string and not an object. So this error should not occur, right? – anand patil May 15 '16 at 13:24
http://jsfiddle.net/S_YOU/E9bU5/240/ - if you pass $index, each function run will be same result for each item. – YOU May 15 '16 at 13:24
no, object or string does not matter, if the same expression run more than limit, it will throw error to prevent infinite loop. – YOU May 15 '16 at 13:26
@YOU - YOU the man!!! – anand patil May 15 '16 at 13:29
It works :) thanks...! – anand patil May 15 '16 at 13:29
@YOU - But I did not get the $index thingy. Could you pls elaborate. – anand patil May 15 '16 at 13:30
its loop(ng-repeat) index, automatically injected by angular - $index, $first $last $middle $odd $even are there too, imo. – YOU May 15 '16 at 14:03
