How can I pass content with script?

I made custom component like this way and used script as well

bm.add('test-block', {

    label: 'Test block',
    attributes: {
        class: 'fa fa-text'
    },
    content: {
        script: "console.log('the element', this)",
        content: "<h1>hello 123</h1>",
        // Add some style just to make the component visible
        style: {
            width: '100px',
            height: '100px',
            'background-color': 'red',
        }
    }
});

then script is working fine but I am not able to select component. Is there any other way to write content with script?
