Error loading custom bootstrap by knockout with RequireJS

Question

I have a custom knockout binding for tooltips, and sometimes this page loads fine, and several times I get this error in the binding.

$ (...). tooltip is not a function

I set a breakpoint in the section where this happens, and sometimes the jquery object does not have any bootstrap functions on it. I can only assume that this is a problem with the loading library load time on demand. As I said, this does not happen every time, and it seems that this happens much more often when I have the developer console open.

Here is my config request

requirejs.config({
    waitSeconds: 200,
    shim: {
        "bootstrap": {
            deps: ['jquery'],
            exports: "$.fn.tooltip"
        }
    },
    enforceDefine: true,
    paths: {
        jquery: 'jquery-1.11.3.min',
        bootstrap: 'bootstrap.min',
        moment: 'moment.min',
        knockout: 'knockout.min',
        appVM: 'appVM',
        custombindings: 'custombindings'
    }
});

And my binding

define(['knockout', 'jquery', 'bootstrap'], function (ko, $, bootstrap) {
    ko.bindingHandlers.tooltip = {
        init: function (element, valueAccessor) {
            var local = ko.utils.unwrapObservable(valueAccessor()),
                options = {};

            ko.utils.extend(options, ko.bindingHandlers.tooltip.options);
            ko.utils.extend(options, local);

            $(element).tooltip(options);  //Error thrown here

            ko.utils.domNodeDisposal.addDisposeCallback(element, function () {
                $(element).tooltip("destroy");
            });
        },
        options: {
            'container': 'body',
            'delay': { 'show': 1000, 'hide': 100 },
            'animation': 'true'
        }
    };
});

My bindings bindings

define(['jquery', 'bootstrap', 'appVM', 'knockout', 'domReady!'], 
    function(jquery, bootstrap, appVM, ko) {
    var vm = new appVM();
    ko.applyBindings(vm);
});

Answer 1

customBindings , ko.applyBindings

define(['jquery', 'bootstrap', 'appVM', 'knockout', 'customBindings', 'domReady!'],
    function(jquery, bootstrap, appVM, ko) {
    var vm = new appVM();
    ko.applyBindings(vm);
});
