How to get an onclick property in Rails form tags?

I am trying to do something so simple, and yet I can't get it to work. 

radio_button_tag(:hw_choice, "Completed", onclick: {alert("I work!"); } )

I need to use radio_button_tag, and what I want to do is to do some js any time the radio button changes. I've tried many varieties of the above, option: { on_click:, none of them even generate the onclick html attribute, so this should be pretty simple, html/rails helper problem.

What am I missing?

radio_button_tag has four parameters, the third parameter is the checked and the fourth parameter is the HTML options you desire.

http://api.rubyonrails.org/classes/ActionView/Helpers/FormTagHelper.html#method-i-radio_button_tag

Add a true or false as the third parameter. Enclose the JavaScript in quotes. Also, you don't need the parentheses around the parameters.

radio_button_tag :hw_choice, "Completed", false, onclick: "window.alert('I work!');"

Similar to this answer, one option is to add an event listener to the button using javascript.

button = document.getElementById("id")
button.addEventListener('click', function(){
    //do stuff here
}, false);

(This solution would be implemented on the frontend rather than the backend, which may not be ideal)
