Suitelet List & Client Script

@NApiVersion

Has anyone been able to add a button to a Suitelet that creates a List and run the function? It seems like the client script is simply not being loaded at all.

I've tries about everything I can think of and my browser is giving me an error that says "Uncaught ReferenceError: require is not defined".

/**

define(['N/ui/serverWidget', 'N/search', 'N/runtime', 'N/url'],
    function(ui, search, runtime, url) {
        function onRequest(context) {
...
              var list = ui.createList({
                    title: 'Funding Liability',
                    style: ui.ListStyle.REPORT,
                    clientScriptFileId: 1077191
                });
...
                list.addButton({
                    id : 'custpage_buttonId',
                    label : 'Test',
                    functionName : "dosomething"
                });
...
