Sending data to an Ember template

I have a question about sending data to an ember template. I have an array with the data :

var data = [ {
    "Coefficients": "Herkomst ouders: Een van de ouders Nederlands en de andere 
     niet Nederlands",
    "Categorie": "Herkomst",
    "Name": "Een van de ouders Nederlands en de andere niet Nederlands",
    "Gewicht": "-0,08943"
  },  {
    "Coefficients": "Type huishouden: Eenouderhuishouden",
    "Categorie": "Type huishouden",
    "Name": "Eenouderhuishouden",
    "Gewicht": "0,49608"
  }]

I have a lot more data in it with diffrent category's (Categorie). In the same file I have this code :

var data_prepped = [];
for (var i = 0; i < data.length; i++) {

  var new_cat = true;
  for (var j = 0; j < data_prepped.length; j++) {
    if (data_prepped[j].Categorie === data[i].Categorie) {
      new_cat = false;
    }
  }

  if (new_cat) {
    data_prepped.push({
      'Categorie': data[i].Categorie,
      'Antwoorden': []
    });
  }

  for (var j = 0; j < data_prepped.length; j++) {
    if (data_prepped[j].Categorie === data[i].Categorie) {
      data_prepped[j].Antwoorden.push({
        'Coefficients': data[i].Coefficients,
        'Name': data[i].Name,
        'Gewicht': data[i].Gewicht,
      });
    }
  }
}

export default Route.extend({
    model() {
        return data_prepped;
    }
}); 

In my template file from ember I run this code :

<section class="category">
                    <h1>Algemeen</h1>
                
                        <h5></h5>
                    <select class="" name="">
                                         
                            <option data-weight="" name="">
                                
                            </option>
                        
                    </select>
                
            </section>

This is working for me but it give me back all the data from the array. But I only want just a part of the data for example this category : "Categorie": "Type huishouden". How can I fix this?
