Name of a custom fuction in Keras model R

问题

I have created a custom loss function:

RMSE= function(y_true,y_pred){
 k_sqrt(k_mean(k_square(y_pred-y_true)))
}

And it works fine but when I run:

model$loss

Get:

<function make_python_function.<locals>.python_function at 0x0000026A51F5c80>

Instead of the name of the loss function, like when I used for example 'mse'

model$loss
"mse"

What should I add to my custom function to be able to get the name?
