angularjs - ui-router controller instantiated again on ui-sref -

i've state link state b. state a's controller contains method declarations , calls on $scope. like:

controller : function($scope) {   $scope.myfunc = { ... }   $scope.myfunc(); } 

when going state b, function $scope.myfunc() called again. why , how avoid? thanks.

update state contains inner $state.go notify , reload set false update parameters. if remove this, transition ok...why?
