SharePoint List Form Textfield to a dropdown - forms

Question

I've found a video from SharePointTech that explains how to change a textfield to a dropdown list on a List Form using data from open API. I'm trying to recreate it, but I'm hitting a roadblock with the new SharePoint Online. Instead of using "Country/Region", I created a new custom list with Company_Name. I took the person's code and made little changes that made a reference to "WorkCountry". When I save the changes (stop editing), the changes do not reflect and I get the same textfield. I had to use SharePoint Designer 2013 to create a new TestNewForm for new entry. Has anyone been able to reproduce this in SharePoint 2013 Designer? If so, would you be able an example?

I use jQuery's ajax method.
Updated code for your reference(you need to change the list name to your list name,InternalName is also):
<script src="https://cdn.staticfile.org/jquery/1.10.2/jquery.min.js">
</script>
<script>
var demo = window.demo || {};
demo.nodeTypes = {
commentNode: 8
};
demo.fetchCountries = function ($j) {
$.ajax({
url: _spPageContextInfo.siteAbsoluteUrl + "/_api/web/lists/getbytitle('Company_Name')/items",
type: "get",
headers: { "Accept": "application/json; odata=verbose" },
success: function (data) {
$j('table.ms-formtable td.ms-formbody').contents().filter(function () {
return (this.nodeType == demo.nodeTypes.commentNode);
}).each(function (idx, node) {
if (node.nodeValue.match(/FieldInternalName="Country_x002f_Region"/)) {
// Find existing text field (<input> tag)
var inputTag = $(this).parent().find('input');
// Create <select> tag out of retrieved countries
var optionMarkup = '<option value="">Choose one...</option>';
$j.each(data.d.results, function (idx, company) {
optionMarkup += '<option>' + company.Title + '</option>';
});
var selectTag = $j('<select>' + optionMarkup + '</select>');
// Initialize value of <select> tag from value of <input>
selectTag.val(inputTag.val());
// Wire up event handlers to keep <select> and <input> tags in sync
inputTag.on('change', function () {
selectTag.val(inputTag.val());
});
selectTag.on('change', function () {
inputTag.val(selectTag.val());
});
// Add <select> tag to form and hide <input> tag
inputTag.hide();
inputTag.after(selectTag);
}
});
},
error: function (data) {
console.log(data)
}
});
}
if (window.jQuery) {
jQuery(document).ready(function () {
(function ($j) {
demo.fetchCountries($j);
})(jQuery);
});
}
</script>

The difference in API will not have a great effect, the key is here '$ j.each (data, function (idx, company) {'. The structure of the return value of different APIs are different, you need to find useful data in return value.
