Golang unescape values in html templates | 东隅已逝/桑榆非晚

While using values in a html template, my colleague faced a problem that the values in <script> tags are all escaped. So the template developer can not use the values in javascript. It just looks like this:
// ... <script type="text/json" id="channel" ch="recommend" tk=""> ["news","comedy","cartoon","tech","travelling","fashion","photograph","household","movies","foods","military","health","test"] </script> // ... I tried to find out the reason. So I copied the template values in other HTML tags rather than in <script>. It rendered correctly, and was not escaped:
// ...

["news","comedy","cartoon","tech","travelling","fashion","photograph","household","movies","foods","military","health","test"]

// ... First, I found some reasons like this, they said using json.Encoder rather than using json.Marshal() directly. So I can SetEscapeHTML(false).
