Passing data into a Vue template

Question

I am fairly new to vue and can't figure out how to add data values within a template. I am trying to build a very basic form builder. If I click on a button it should add another array of data into a components variable. This is working. The I am doing a v-for to add input fields where some of the attributes are apart of the array for that component. I get it so it will add the input but no values are being passed into the input.

I have created a jsfiddle with where I am stuck at. https://jsfiddle.net/a9koj9gv/2/

<div id="app">
    <button @click="add_text_input">New Text Input Field</button>
    <my-component v-for="comp in components"></my-component>
    <pre>{{ $data | json }}</pre>
</div>

new Vue({
    el: "#app",

    data: function() {
        return {
            components: [{
                    name: "first_name",
                    showname: "First Name",
                    type: "text",
                    required: "false",
                    fee: "0"
                  }]
            }
    },

    components: {
        'my-component': {
            template: '<div>{{ showname }}: <input v-bind:name="name" v-bind:type="type"></div>',
            props: ['showname', 'type', 'name']
        }

    },

    methods: {
        add_text_input: function() {
            var array = {
                    name: "last_name",
                    showname: "Last Name",
                    type: "text",
                    required: "false",
                    fee: "0"
                  };
            this.components.push(array);
        }
    }
})

I appreciate any help as I know I am just missing something obvious.

Thanks

Use props to pass data into the component.

Currently you have <my-component v-for="comp in components"></my-component>, which doesn't bind any props to the component.

Instead, do:

<my-component :showname="comp.showname" 
              :type="comp.type" 
              :name="comp.name" 
              v-for="comp in components"
></my-component>

Here is a fork of your fiddle with the change.
