ng-bind + function

[samuel....@ouvanous.com]

Hi, 

I am new to angular and would like to understand how i can achieve this. 

I use rdf.js as data model and want to do something like that http://jsfiddle.net/ouvanous/bDEYd/14/

When i did this i notice that the call to get method is done two times and i don't understand why ? 

Also i don't think that that this is the best way ? 

Thanks, by advance for any advice.

Samuel, 

Would need a bit more context as to what you are trying to accomplish.  However, you do point out an interesting issue. I played around with your fiddle 

http://jsfiddle.net/dandoyon/TR6VP/2/

I added a second controller which checks the number of times the controller is called and if 'get' has been called more than once it returns at beginning of call. Interestingly, your original controller now gets called not twice but three times and adding the 'times' check prevents the view from rendering properly. 

Unless I'm missing something, there is no reason why you shouldn't be able to bind this way, in fact, it is encouraged.

I'm curious as to what the devs say

Yes we call everting over and over until we are sure that the model is stable. That usually means 2 iterations. For this reason your getter function needs to be supper quick. If it is not, then you need to precompute the result and bind to the precomputed value.
