delete multiple records on EmberJS using

I would like to have an action that prints all the selected check-boxes on my table to the console.

in my controller I have

removedSelected: function() { let selected = this.filterBy('isSelected', true); console.log(selected); }

in my template file I have

I have setup my controller to filter all the records that are "isSelected" in the table by using input helper on ember.

I am getting an error on the console which states this.filterBy is not a function

Do i need to setup an array to handle this first?

Below is more of the code for a better picture.

Thanks!
