qtip on a Grid cell

[Radius-Service]

How to display a hint?
In "Extjs 3" worked the following way

renderer: function (value, metadata, record, rowIndex, colIndex, store) {
  metadata.attr = 'ext:qtip="' + value + '"';
  return value;
} 

But in the new version is not "metadata.attr" and "ext:qtip".

I solved the problem this way:

return "<div data-qtip='my <b>title</b>'>"+value+"</div>"; 

Is this the right way? Or is there a good one?

// Add a quick tip to an HTML button
<input type="button" value="OK" data-qtitle="OK Button" data-qwidth="100"
     data-qtip="This is a quick tip from markup!"></input>

so basically

metadata.attr = 'data-qtip="' + value + '"';

should work.

Ignoring the escaping issues it would be:

renderer: function(value, metaData) {
    metaData.tdAttr = 'data-qtip="' + value + '"';
    return value;
}

Thanks, skirtle response is more accurate in the matter.
