I made a simple model getting data from an API but to retrieve data need to activate it with a button. I made and function and button's tag "" and it is not showing up on the view.

class ToggleSync(models.Model):
    _name = "hotel.sync"
    _description = "ToogleSync"

    sync = fields.Boolean("Sync or Not")
    api_token = fields.Char("API Token")

    # Define the method to be called when the button is clicked
    # @api.multi
    def _compute_get_data(self):
        for record in self:
            print("wassup")

Sorry I have some time not working on Odoo and I have no idea what is wrong.

Edit: Editor not working with xml code. xml code always disappears.

Edit 2: button name="_compute_get_data" string="Get Data" class="btn-primary"                 type="object"

Edit 3: Reinstalled the module and it showed up
