Global function for Meteor template helper

I have registered a global function like this:

Handlebars.registerHelper('dialogBoxOptions', function (callbackFunctionName){
    return {
        callBack: callbackFunctionName
    };
});

but when I try to access it as below I get dialogBoxOptions is not defined

Template.myLlist.helpers({
    dOpt: dialogBoxOptions('dlgCB')
});

I have tried this as a global handlebars helper and a regular javascript function but get the same result.

In Meteor 1.0+ it looks like the syntax for creating a global helper is now:

Template.registerHelper('functionName',function(param1,param2){
  ... your code here ...
})

Then use it anywhere on the client with:

var result = Blaze._globalHelpers.functionName(param1, param2);

OTOH, the UI object doesn't appear in the current documentation so I'm left wondering if this usage is blessed.

You can't access handlebars helpers this way you can access them in the template:

<template name="myList">
     {{dialogBoxOptions.callback 'something'}}
</template>

If you want to access it in your helper like you are doing now you should register a global method instead. You could put this in a file like /lib/helpers.js

dialogBoxOptions = function (callbackFunctionName){
    return {
        callBack: callbackFunctionName
    };
}

Also if you want to make a global template helper, the syntax is now:

Template.registerHelper("dialogBoxOptions", function (param2) {
    return true;
});

Use Template.registerHelper(name, function)
As shown in Meteor Documentation

There is now a way to get access to the registered global helpers.

//Register the helper
UI.registerHelper("functionName", function (param1, param2) {
  return true;
});

//Use the helper elsewhere
var result = UI._globalHelpers('functionName')(param1, param2);
