Iterating over itemControllers init function

I'm iterating over itemControllers init functions verifying a specific condition. What should I do if I want to stop iterating when the condition has changed? By iterating, I mean going over every single itemController inits function. Example :

init: function(){

    if(getCurrentConvId()){ 
        var self = this;
        return;

        if(self.get('model').id == getCurrentConvId()){
            self.get('controllers.conversation').set('selectedConv', this.get('model'));
            self.send('clickConv', self.get('model'));

            **Here I would like to stop iterating because conv has been found**
        }           
    }   
},

An idea I had was to put an observer on a convFound property in the ArrayController but the problem is that the code on init functions will be executed before the observer is even part of the app. Any suggestions?
