How do I pass resizable onMove function in data-gjs-resizable attribute

onStart event is working fine while creating component but I want to add it while creating block. Here is  my code: 

const keyWidth = 'flex-basis';
const step = 0.1;
const minDim = 1;
const currentUnit = 1;

const resizerRight = {
        tl: 0, tc: 0, tr: 0, cl: 0, bl: 0, br: 0, cr: 1, bc: 0, keyWidth, currentUnit, minDim, step }

const attrsToString = attrs => {
        const result = [];

        for (let key in attrs) {
            let value = attrs[key];
            const toParse = value instanceof Array || value instanceof Object;
            value = toParse ? JSON.stringify(value) : value;
            result.push(`${key}=${toParse ? `'${value}'` : `"${value}"`}`);
        }

        return result.length ? ` ${result.join(' ')}` : '';
    }

const attrsCell = attrsToString(colAttr);

if (c.blocks.grid) {
        bm.add('grid', {
            label: `
            <div class="gjs-block-label">Grid</div>
        `,
            category: 'Basic',
            attributes: { class: 'gjs-fonts gjs-f-b3' },
            content: `
            <div class="container">
                <div class="row" data-gjs-selectable="false" data-gjs-hoverable="false" data-gjs-droppable="false" >
                    <div ${attrsCell}></div>
                    <div ${attrsCell}></div>
                    <div ${attrsCell}></div>
                </div>
            </div>
        `
        });
    }
