correct handle the 'params' arg

[languanghao]

ko.intValue.extend({min:{
params: 3,
message: 'some messages'
}})

Above code won't work correct, because the code not correct handle the params, the 'min' validator get the params as a object, not the 'params' value 3.

@crissdev I have update the code.

The code below dose not work as excepted.

ko.field.extend({
  min: {
      params: 3
  }
});

I am writing a wtforms extentions with ko validation. In my code, I need to dynamic add validation rules to ko fields. My code like this:

var extend = {}
extend[ruleName] = {}
if (hasParams){
    extend[ruleName] = {'params': params}
else{
    extend[ruleName] = {'params': true}
}

I foud my problem was occurred because code of addExtender: function (ruleName) line 509 in knockout.validation.js. It seems like if a rule only have one params, you must write it as {ruleName: paramValue}, but not {ruleName: {params: paramValue}}.

Thanks for all the info. I believe this feature is already implemented in v2.1.0 branch. See #554 and #561.

Here's the updated example which uses the library from that branch http://jsfiddle.net/crissdev/9xqmrLs8/1/
