Function calls aren't recommended in templates as there are called on each change detection.

On refresh/loads the component will be initialized. You can initialize a local property of your component with related data

how i can do that?

#

#

Please provide more context firstly: your function doesn't do anything here.

#

What do you want to display in the template?
