To call a method from the odoo python model you have Model().call() in javascript.

For example think of following model in py file.

class group_js(models.Model):
   _name = "model.example"
   _description = "Example model"

   def get_record(self):
       return ''

And from the javascript file you can call it as:

new Model("model.example").call("get_record",[args]).then(function(result){ 
    console.log(result);//show in console Hello
});

Here the further details of call method:

/**
 * Call a method (over RPC) on the bound OpenERP model.
 *
 * @param {String} method name of the method to call
 * @param {Array} [args] positional arguments
 * @param {Object} [kwargs] keyword arguments
 * @param {Object} [options] additional options for the rpc() method
 * @returns {jQuery.Deferred<>} call result
