How to add a tracking number in my account page

We can add a tracking number column in the purchase history page and when the billing is done corresponding the tracking number will be displayed for the billed item

entry file

_.extend(RecordViewsActionableView.prototype, {
				getContext: _.wrap(RecordViewsActionableView.prototype.getContext, function (fn) {
					var original = fn.apply(this, _.toArray(arguments).slice(1));
					console.log("this", this);
					console.log("this", original);
					var trackingNumbers =this.model.get('trackingNumbers')
					if(trackingNumbers&&trackingNumbers.length!=0){
						original.trackingNumbers=trackingNumbers.toString()
					}
					return original;
				})
			});

In tpl for displaying the heading as tracking no

<th class="order-history-list-recordviews-actionable-{{type}}-header">
					<span>{{translate 'Tracking No'}}</span>
				</th>

In tpl for display the value of the tracking number

<td class="recordviews-actionable-actions-1">
		<p class="recordviews-actionable-value">{{trackingNumbers}}</p>
	</td>
