Ember load variable everytime page is loaded

I want a variable called "name" in my router or controller , which i will use in my hbs template. Right now , I'm doing this. But the get() is not loading if i navigate backward and click the link to the current page again. It only loads the first time and if i refresh the page . Due to this, the value of name in my form is not reloading everytime i hit the page.

      #controller
      name: computed('model.name', {
        get() {
          return this.get('model.name');
        }
      })



      #.hbs
      
      <button >Update Post</button>
