Pass Visualforce input fields to Controller - get Unknown property 'AccountStandardController.CallCycle__c'

Question

I am struggling to get my simple VF page to work as I keep getting an 'Unknown property 'AccountStandardController.CallCycle__c' error. Below is my VF form, and below that my Controller. I first tried just having the 2 variables CCStart and CCEnd and to use those on the form, but that also didn't work - I get the error 'Could not resolve the entity from <apex:inputField> value binding '{!CCStart}'. <apex:inputField> can only be used with SObjects, or objects that are Visualforce field component resolvable'. I then changed it to using the custom object instead, but that throws the other error. Please tell me where I'm going wrong - using the variables would be better, as I only need those for my query.

<apex:page StandardController="Account" extensions="AccountContactListRequestController" sidebar="true" showHeader="true">
<apex:form >
    <apex:sectionHeader title="Account Contacts Print" subtitle="Request a print of Contacts for Accounts/Call Cycle range" />

        <apex:pageBlock >
            <apex:PageMessages />

            <apex:pageBlockButtons >
                <apex:commandButton id="Print" value="Print Contacts" action="{!PrintContacts}" />
                <apex:commandButton id="Clear" value="Clear" action="{!Clear}" />
            </apex:pageBlockButtons>

            <apex:pageBlockSection title="Call Schedule Cycle Details" columns="1">

                <apex:inputField id="account" label="Account" value="{!Acct.Name}" required="true" />
                <apex:inputField id="cycleStart" label="Call Cycle Start" value="{!CallCycle__c.CycleStart__c}" />
                <apex:pageBlockSectionItem></apex:pageBlockSectionItem>
                <apex:inputField id="cycleEnd" label="Call Cycle End" value="{!CallCycle__c.CycleEnd__c}" />

            </apex:pageBlockSection>

The __C seems to be culprit .You will need to use exact variable names as you have declared as a getter and setter variable.Using __c will mean SFDC compile time engine will look your variable as standard field on the Account record .Below is the corrected piece of code

<apex:inputField id="cycleStart" label="Call Cycle Start" value="{!CallCycle.CycleStart__c}" />
  <apex:pageBlockSectionItem></apex:pageBlockSectionItem>
 <apex:inputField id="cycleEnd" label="Call Cycle End" value="{!CallCycle.CycleEnd__c}" />
