I have a inline html field on Suitelet and have button in inline html field. I want to run function in client script and how can I do that in 2.0?

inlineField.defaultValue = '<input type="radio" name="testing_radio" value="testing" onclick="testingFunc(this)">Testing'
form.clientScriptModulePath = '/ClientScript.js';

In client script

function testingFunc(elm){
}

return {testingFunc:testingFunc, pageInit:_pageInit}

When that input button is clicked it shows me testingFunc is not defined error message

Why are you not using the form.addButton() API?

not only button but like Radio or checkbox for better UI

your question is equivalent to asking why does

(function () {
  function testingFunc(elm) {}

  return { testingFunc: testingFunc };
})();

testingFunc();

throw the not defined error message

Thank you for your information but why it works if use native NS button?

form.addButton({
label:'TESTING',
functionName: "testing"
})

form.addField({type:'inlinehtml', ... }).defaultValue = "<button onclick="testing()">TESTING</button>"

I can see in testing function is defined in chrome developer mode? and they are in same scope?

take a look on the onclick that netsuite adds

Okay. I really appreciate your help
