Parse html syntax to golang template

hi everyone, i have problem to view html format within go template.
i have services that return values, i insert
to one of them like this :

func ToProduct(product ProductModel.Product) ProductResponse {
	return ProductResponse{
		Code:        product.Code,
		Title:       product.Title,
		Description: product.Description,
		Qty:         product.Qty,
		Price:       product.Price,
		Price1:      product.Price1,
		ShortNotes:  product.ShortNotes,
		Notes:       strings.Replace(product.Notes, ",", "<br>", -1),
		Image:       "/assets/img/products/" + product.Code + ".jpg",
		DivName:     product.DivName,

in html template, i put this

{{ .product.Notes }}

but the result
appear like original text not new line

Invalid JSON!
Error: Parse error on line 1:
ProductResponse{ C
Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[', got 'undefined'

Just log the json output of the vars

can you explain, sorry i dont get it

Add log to your packahe or just fmt.Println whats is in your vars…
