Warning that `Id` exists and must be destroyed

In most cases, I see the following warning when I press the same button more than once (when calling the same function twice or more)

[WARN] [WARN][Ext.Component#constructor] Registering a component with a id (`name`) which has already been used. Please ensure the existing component has been destroyed (`Ext.Component#destroy()`.

How should I destroyuse this warning? or how to fix it?

UPDATE

function onPersonFound(imageData) {
           var image = Ext.create('Ext.Img', {
                                 src: "data:image/jpeg;base64," + imageData,
                                 id: 'logo',
                                 width: 372,
                                 height: 140
                                 });
