Cyclic dependency using Knockout subscribe

Question

Is there any possible fix to the below code where I face cyclic dependency using Knockout.js subscribe.

this.observable1.subscribe(function(value){
self.observable2("someValue");
});

this.observable2.subscribe(function(value){
self.observable1("someValue");
});

Where "self" is an alias to "this" and observable1 linked to combo box, and observable2 linked to date picker.

Kindly suggest

As @Origineil said, you probably need to re-think your solution.

But if you really want to keep current solution, you could use a flag to break the cycle.

var isInnerUpdate = false;

this.observable1.subscribe(function(value){
  if (isInnerUpdate) {
    isInnerUpdate = false;
  } else {
    isInnerUpdate = true;
    self.observable2("someValue");
  }
});

this.observable2.subscribe(function(value){
    if (isInnerUpdate) {
    isInnerUpdate = false;
  } else {
    isInnerUpdate = true;
    self.observable1("someValue");
  }
});
