How do you get AngularJS to bind to the title attribute of an A tag?

The issue here is your version of AngularJS; ng-attr is not working due to the fact that it was introduced in version 1.1.4. I am unsure as to why title="{{product.shortDesc}}" isn't working for you, but I imagine it is for similar reasons (old Angular version). I tested this on 1.2.9 and it is working for me.

As for the other answers here, this is NOT among the few use cases for ng-attr! This is a simple double-curly-bracket situation:

<a title="{{product.shortDesc}}" ng-bind="product.shortDesc" />

Look at the fiddle here for a quick answer

data-ng-attr-title="{{d.age > 5 ? 'My age is greater than threshold': ''}}"

Displays Title over elements conditionally using Angular JS

Sometimes it is not desirable to use interpolation on title attribute or on any other attributes as for that matter, because they get parsed before the interpolation takes place. So:

<!-- dont do this -->
<!-- <a title="{{product.shortDesc}}" ...> -->

If an attribute with a binding is prefixed with the ngAttr prefix (denormalized as ng-attr-) then during the binding will be applied to the corresponding unprefixed attribute. This allows you to bind to attributes that would otherwise be eagerly processed by browsers. The attribute will be set only when the binding is done. The prefix is then removed:

<!-- do this -->
<a ng-attr-title="{{product.shortDesc}}" ...>

(Ensure that you are not using a very earlier version of Angular). Here's a demo fiddle using v1.2.2:

It looks like ng-attr is a new directive in AngularJS 1.1.4 that you can possibly use in this case.

<!-- example -->
<a ng-attr-title="{{product.shortDesc}}"></a>

However, if you stay with 1.0.7, you can probably write a custom directive to mirror the effect.
