Backbone model with a function in defaults returning object to use in jquery template

I have a model something like this and I want to access those object's key's values in a jquery template

var Item = Backbone.Model.extend({
  
        defaults : {
                name : "abc"
                designation: "def"
        },

        defaults : {
          
                foo: function (obj) {
                      return {
                          child1: {
                             childName: "Mike",
                             childAge: 20
                          },
                          child2: {
                             childName: "Tom",
                             childAge: 10
                          }
                      };
                }
        }
});

And a jquery template where I want to access those values something like this

<script type="text/x-jquery-tmpl" id="temp1">
    {{ if child1.childAge > 18 }}      
       <p> Allowed </p>
    {{ else }}
       <p> Not Allowed </p>
    {{ /if }}
</script>

I tried this.model.toJSON() but the I'm not able to access those object values like child1.childName like I can access "name" and "designation"

How can I access those?

You can not have two defaults properties in your object and a , is missing after name : "abc".

defaults will copy to your instante the return value of a function if is defined in this way, or the properties of an object if is defined in this way. But if you your object have functions, it will be copied as is, not executed, and copying the return values.

I'm not sure what exactly you are trying to achieve, at it seems that you must work with collection and nested models.

But answering your actual question, this should workd:

const Item = Backbone.Model.extend({
    defaults : function() {
        return {
            name: "abc",
            designation: "def",
            child1: {
                childName: "Mike",
                childAge: 20
            },
            child2: {
                childName: "Tom",
                childAge: 10
            }
       }    
   },
});

const item = new Item()
console.log(item.toJSON())
