My api call returns html, but if that html is empty e.g. I get a console html response of "", I want to display a default message using knockout. So I'm guessing that it needs to recognise that "" is empty and then display my alternate content.  

**View model -**

```
    var MyText = ko.observable(); 

    var company = shell.authenticatedCompany();
    hazibo.helpTextGet(company.name, company.userName, company.password).then(function (data) {
        MyText(data);  
    });

return {
    MyText: MyText

```

};

**View -** 

```
<section class="help-text">
    <div class="flex-container">
        <div class="flex-item" data-bind="html: MyText">This is my alternate message if the html response is ""</div>
    </div>
</section>

```
