The parent component invokes the child component function and executes the

clusterize() {
      return new Clusterize({
        rows: this.DomArray,
        scrollId: this.scrollId,
        contentId: this.contentId,
        rows_in_block: this.rows_in_block,
        blocks_in_cluster: this.blocks_in_cluster,
        show_no_data_row: this.show_no_data_row,
        no_data_text: this.no_data_text,
        no_data_class: this.no_data_class,
        keep_parity: this.keep_parity,
        tag: this.tag,

        callbacks: (Clusterize.prototype.callbacks = {
          // 
          clusterWillChange: function() {
            console.log("----->------>");
          },
          // 
          clusterChanged: function() {
            console.log("----->-------->");
          },
          // 
          scrollingProgress: function(progress) {
            console.log(progress);
          }
        })
      });
      
      

  1. you want to add a callback to the function in callbacks. You can pass the function directly when the parent component calls it, and let the child component execute it.
