Angularjs Sharepoint Rest API to showing all columns

Question

I have created a very basic controller to pull data from a SharePoint list, but it only pulls the base Title and created column. It doesn't pull any columns I have created, which are the ones I require. Is there a setting in SP itself to state it is available for the API?

 

<div ng-app="listApp">
    <div id="App1" ng-controller="controller1">
        <h1>First List Items</h1>
        <div ng-repeat="item in items">
            <p>{{item.Title}}</p>
        </div>
    </div>
</div>

 

var appVar = angular.module('listApp', []);

appVar.controller("controller1", function($scope){
    GetListItems($scope, "List1");
});

function GetListItems($scope, listName){
    $.ajax({
        url: "https://example.com/sites/mysite/_api/web/lists/GetByTitle('"+listName+"')/items",
        method: "GET",
        async: false,
        headers: { "Accept": "application/json;odata=verbose" },
        success: function(data){
            $scope.items = data.d.results;
        },
        error: function(sender,args){
            console.log(args.get_message());
        }
    });
}
