How to call RequireJS functions in other files? How to separate RequireJS
files?

Instead of having one giant js file that has a whole bunch of "defines",
how do I call my various "define" functions from other files?
I've been copying these examples, but still cannot get it to work:
example-multipage
example-multipage-shim
example-jquery-shim
Here is what I have so far:
main.js
require.config({
baseUrl: '',
paths: {
jquery: '../libraries/jquery-1.10.2.min',
simControlView: '../javascripts/simControlView'
}
});
require(['jquery','loadPage'], function( $,loadPage)
{
loadPage();
});
define('loadPage', ['jquery'], function($)
{
var simControlView = require(['./simControlView']);
return function()
{
simControlView.showSimControlView(); //having problem here
};
});
simControlView.js
define(['jquery'], function ($) {
return {
showSimControlView: function () {
console.log("Hi!!");
}
}
});
Here is the error that I'm getting:
Uncaught TypeError: Object function d(e,c,h){var
g,k;f.enableBuildCallback&&(c&&H(c))&&(c.__requireJsBuild=!0);if("string"===typeof
e){if(H(c))return v(A("requireargs", "Invalid require
call"),h);if(a&&s(N,e))return Ne;if(j.get)return
j.get(i,e,a,d);g=n(e,a,!1,!0);g=g.id;return!s(r,g)?v(A("notloaded",'Module
name "'+g+'" has not been loaded yet for context: '+b+(a?"":". Use
require([])"))):r[g]}K();i.nextTick(function(){K();k=q(n(null,a));k.skipMap=f.skipMap;k.init(e,c,h,{enabled:!0});C()});return
d} has no method 'showSimControlView'
See anything I'm doing wrong? Any help is appreciated!
