How to display src of image component?

here is my code 

`bm.add( 'image', {
        label: opt.imageBlkLabel,
        category: opt.categoryElementsLabel,
        content: {
            type: 'image',
            src: 'http://placehold.it/250x150/78c5d6/fff/',
            style: {color:'black'},
        },
        attributes: {
            class:'gjs-fonts gjs-f-image'
        }
    });`

i used this with the latest version of grapesjs it stops working with the latest version 
when i drag and drop image component on canvas it appears nothing but element is still on canvas 
and when i click on toggle image button 2 times it gives me result as expected.
