How to use the view.call function in view

function Dashboard() {
  if (!(this instanceof Dashboard)) {
    return new Dashboard();
  }

  // Define template
  View.call(this, template);


/**
 * Model of each item on the list.
 * @type {Array}
 */
  this.items = [];

  this.loadItems();
}

function DiffView() {
  if (!this instanceof DiffView) {
    return new DiffView();
  }

  View.call(this, template);
  this.sections = [];
}

function DeploymentView(locals) {
  if (!(this instanceof DeploymentView)) {
    return new DeploymentView(name);
  };

  View.call(this, template, locals);

  this.url = locals.url;
}

function HeaderView() {
  View.call(this, template);

  this.user = this.el.find('.user');
}

function Dashboard() {
  if (!(this instanceof Dashboard)) {
    return new Dashboard();
  };

  View.call(this, template, { motto: t('dashboard.motto') });

  /**
   * DOM elements
   */

  this.elDeployments = this.el.find('.deployments')[0];

  /**
   * View model
   */

  this.deployments = [];

  /**
   * Startup
   */

function ItemView(item) {
        var element = tmpl.cloneNode(true);
        element.querySelector('.name').textContent = item.name;
        View.call(this, item, element);
        this.bind('click .remove', 'remove');
        this.bind('click .done', 'complete');
      }
