How to mutate an array's value in “each” helper (Octane)

@Murali wrote:

I have an array of strings passed as an argument to a component, inside the component I am using “each” helper to render each string in a text input. I tried the following approach.

MainComponent.hbs
<Component @model={{model}}/>

//Eg: model.list = ["Jack", "Sparrow"];

Component.hbs
<div>
    {{#each this.args.model.list as |name|}}
    <div>           
         <PaperInput @value={{ name }} 
            @placeholder="Enter a Name"
            @onChange={{action (mut name)}}/>        
    </div>
    {{/each}}
</div>

I am running into the error “Uncaught (in promise) Error: Assertion Failed: You can only pass a path to mut”. Would really appreciate if anyone can let me know What’s going wrong here.
