Unable to use 'condition'

I am using angular2-json-schema-form and trying to make use of the ‘condition’ functionality. In the playground examples for ASF there is the ‘Hack: Conditional Required’ example:

{
  "schema": {
    "type": "object",
    "properties": {
      "switch": {
        "title": "Spam me, please",
        "type": "boolean"
      },
      "email": {
        "title": "Email",
        "type": "string",
        "pattern": "^\\S+@\\S+$",
        "description": "Email will be used for evil."
      }
    },
    "required": [
      "switch"
    ]
  },
  "form": [
    {
      "type": "help",
      "helpvalue": "<p>Schema Form does not support oneOf (yet), but you can do a workaround and simulate certain scenarios with 'condition' and 'required'  (and/or 'readonly') in the form.</p>"
    },
    "switch",
    {
      "key": "email",
      "condition": "model.switch",
      "required": true
    },
    {
      "key": "email",
      "condition": "!model.switch"
    },
    {
      "type": "submit",
      "style": "btn-info",
      "title": "OK"
    }
  ]
}

I have found that both fields are displayed, and the value of ‘condition’ appears to have no effect?

I actually wanted to show the second item only when the user clicks on No. At the same time I want the value of the No to be false. I was trying with negation, It did working. I used the above example and was able to fix it. Thank you @pdinesh80 !!

Issue:

        { 
          "key": "isLastDateOver", 
          "title": "Is last date over?", 
          "type": "radios",
          "inline": true,
          "titleInline": true,
          "titleMap": {
            "true": "Yes",        
            "false": "No"
          }
        }, 
        { 
          "key": "lastDate",
          "type": "date",
          "title": "Last Date",
          "condition": "!model.isLastDateOver",
          "required": true  
        }

Solution:

        { 
          "key": "isLastDateOver", 
          "title": "Is last date over?", 
          "type": "radios",
          "inline": true,
          "titleInline": true,
          "titleMap": {
            "true": "Yes",        
            "false": "No"
          }
        }, 
        { 
          "key": "lastDate",
          "type": "date",
          "title": "Last Date",
          "condition": {
            "functionBody":"try { return !model.isLastDateOver } catch(e){return false}"
          } 
        }

@dschnelldavis Condition works fine as from the example, have a question Can i use condition on string fields instead of boolean and check for expression? for example

{ “schema”: { “type”: “object”, “properties”: { “text”: { “title”: “Spam me, please”, “type”: “string” }, “email”: { “title”: “Email”, “type”: “string”, “pattern”: “^\S+@\S+$”, “description”: “Email will be used for evil.” } }, “required”: [ “switch” ] }, “form”: [ { “type”: “help”, “helpvalue”: “

Schema Form does not support oneOf (yet), but you can do a workaround and simulate certain scenarios with ‘condition’ and ‘required’ (and/or ‘readonly’) in the form.

” }, “switch”, { “key”: “email”, “condition”: “model.text==‘hello’”, “required”: true }, { “key”: “email”, “condition”: “model.text!=‘hello’”, }, { “type”: “submit”, “style”: “btn-info”, “title”: “OK” } ] }

UPDATE: From this link https://github.com/dschnelldavis/angular2-json-schema-form/issues/146, found a work around

so we can have condition like this

"condition":{
                        "functionBody":"try { return model.text=='test'} catch(e){return false}"
                    },
