jquery - How can I list the uploads from a YouTube Channel?

I am writing this code to search youtube channels on my website and then list their uploads after clicking on them. However currently my links all on all channels to the last channel listed's uploads and I cant tell how in my code that allows that to happen. Can someone have a look and give me an idea of what is going wrong. You can also try/see the website on www.youtubebypass.dx.am

Once you have the channel_id, change the highlighted letter as is shown:

Channel: Microsoft Hololens

Channel_id: UCT2rZIAL-zNqeK1OmLLUa6g

Uploads (playlist): UUT2rZIAL-zNqeK1OmLLUa6g

Once you have the uploads playlist, you can use this request for get the uploaded videos:

https://www.googleapis.com/youtube/v3/playlistItems?part=snippet%2CcontentDetails&playlistId=<UPLOAD_PLAYLIST_ID>&fields=items(contentDetails(videoId%2CvideoPublishedAt)%2Csnippet(publishedAt%2Ctitle))&key={YOUR_API_KEY}

And these are the results:

{
 "nextPageToken": "CAUQAA",
 "pageInfo": {
  "totalResults": 61,
  "resultsPerPage": 5
 },
 "items": [
  {
   "snippet": {
    "publishedAt": "2019-02-24T17:38:51.000Z",
    "title": "Industry Partner Solutions for Microsoft HoloLens 2"
   },
   "contentDetails": {
    "videoId": "FWYcuHUgcng",
    "videoPublishedAt": "2019-02-24T17:38:51.000Z"
   }
  },
  {
   "snippet": {
    "publishedAt": "2019-02-24T17:32:14.000Z",
    "title": "Introducing Microsoft HoloLens 2 (Audio Description)"
   },
   "contentDetails": {
    "videoId": "NtRGESjKT6M",
    "videoPublishedAt": "2019-02-24T17:32:14.000Z"
   }
  },
  {
   "snippet": {
    "publishedAt": "2019-02-24T17:31:30.000Z",
    "title": "Introducing Microsoft HoloLens 2"
   },
   "contentDetails": {
    "videoId": "eqFqtAJMtYE",
    "videoPublishedAt": "2019-02-24T17:31:30.000Z"
   }
  },
  {
   "snippet": {
    "publishedAt": "2019-02-24T17:39:08.000Z",
    "title": "PACCAR is exploring Dynamics 365 Guides and HoloLens 2 to improve employee onboarding"
   },
   "contentDetails": {
    "videoId": "OQDhTtDgir0",
    "videoPublishedAt": "2019-02-24T17:39:08.000Z"
   }
  },
  {
   "snippet": {
    "publishedAt": "2019-02-24T17:41:16.000Z",
    "title": "Introducing Dynamics 365 Guides for HoloLens 2"
   },
   "contentDetails": {
    "videoId": "V8c3pDKdHEc",
    "videoPublishedAt": "2019-02-24T17:41:16.000Z"
   }
  }
 ]
}

This is the Google API Explorer demo I made.

N.B, this channel has 61 uploaded videos and the maximun results per page are 50.

This is the entire working jsfiddle.
