below part of controller

.controller('adminuserscontroller', ['$rootscope', '$scope', '$state', '$stateparams', '$modal', '$log', '$timeout', 'usersapi', 'policiesapi','workspacesapi', 'msg', '$filter',   function($rootscope, $scope, $state, $stateparams, $modal, $log, $timeout, usersapi, policiesapi, workspacesapi,msg, $filter) {     var self = this,       limit = 100, ....   $scope.select = function (item) {       console.log('********* select ');       $scope.user.full_name = item.full_name;       console.log('foo', item);     };     // initialize page     self.refresh(); ... 

assuming you're using angularstrap typeahead,
trigger user input have :

$scope.$on('$typeahead.select', function(event, value, index, elem){      $scope.user.full_name = value; });
