Suitescript 2.0 addButton

Question

I have a suitelet with a sublist button and I am trying to get the button to execute a function on a custom module. I can not get it to work. I get an error "Cannot call method "receive" of undefined" Any Ideas?

Snippet of code to add button

define(['N/error', 'N/record', 'N/search', 'N/ui/serverWidget','./lib1'],


function(error, record, search, ui, lib1) {
//... some code here
searchSublist.addButton({
			id: 'custpage_recievepayment', 
			label: 'Receive Payment',
			functionName: "lib1.receive()"});
}

Snippet of custom Module

define(['N/redirect'],
		function(redirect){
	function receive(){

    		var deal = '497774';
    		var url = redirect.toSuitelet({
    			scriptId: 'customscript_deal_entry_2_0',
    			deploymentId: 'customdeploy1',
    			returnExternalUrl: false,
    			params: {
    				prevdeal: url
    			}
    		})
	}
	});

Answer 1

I was able to get this to work with out the client script or exporting it to the global object that was suggested. The key was to modify my custom module to return the function I wanted to use on the button and calling the custom module file with form.clientScriptFileId

//suitelet
define(['N/error', 'N/record', 'N/search', 'N/ui/serverWidget'],
function(error, record, search, ui) {
   
	// other code here
		form.clientScriptFileId = 78627;//this is the file cabinet internal id of my custom module
		var searchSublist = form.addSublist({
			id: 'custpage_deals',
			type: ui.SublistType.LIST,
			label: 'Deals'
		})
		searchSublist.addButton({
			id: 'custpage_receivepayment', 
			label: 'Receive Payment',
			functionName: "receive()"
				});
  
  //custom module
  
  define(['N/url','N/error'],

function(url, error) {
	return{
    	  receive: function(){
    				
     //function code here
	}		           

})
