Re: [KnockoutJS] Knockout.js - every click databind called twice... make this pain go away please....

..and every post sent thrice! ;)

.NET 4.5, MVC5 and WebApi2 can not reasonably have anything to do with this. Any way you could possibly show us the problem "in action"?

I have been trying to debug this for days with no solution.

I have an MVC5 app and using Knockout 2.3 and Jquery 1.10.    Whenever I click a button in my view's html (not in a form, just a button that is type="button" or "submit"), and that button's  click is  databound to a function in my viewmodel,  that viewmodel function gets called  twice??  I see the debugger shows that as well as Fiddler.   

 I set clickBubble to false... does not make a difference.  I stepped through the debugger and  KO properly sets   the e.prevent... parameters to false...

Any ideas?  Please, if  the suggestion is to use a different version of KO or Jquery,  please let me know you have actually tested those versions work with.net 4.5,  MVC5 and WebApi2.  Otherwise I am down another rabbit hole.  

Thanks in advance

Use bind, passing parameters to the bind method:

 

data-bind="click: $root.myFunction.bind($data, $data)"
