{!input}'. can only be used with SObjects, or objects that are Visualforce field component resolvable

Hello,

My component code is
  
<apex:component >
<apex:attribute name="label" description="" type="String" required="true"/>
<apex:attribute name="input" description="" type="sObject" required="true"/>
<div class="form-group col-md-6">
  <label for="input" class="col-md-2 control-label">{!label}</label>
  <div class="col-md-6 form-control-wrapper">
    <apex:inputField styleClass="form-control" id="input" value="{!input}" />
    <span class="material-input"></span>
  </div>
</div>
</apex:component>
When I use this, I get this error

Error: Could not resolve the entity from value binding '{!input}'. can only be used with SObjects, or objects that are Visualforce field component resolvable.

What binding am I missing?

As the error message itself suggests, the problem here is that your <apex:inputField> is not really associated with any valid field in sObject.

Try changing your code to something along these lines and it should work.
  
<apex:component>
    <apex:attribute name="MyObj" type="sObject" description=""/>
    <apex:attribute name="MyObjField" type="String" description=""/>
    <apex:inputField value="{!MyObj[MyObjField]}"/>
</apex:component>

Hi Narinder,

Try by changing this line <apex:inputField styleClass="form-control" id="input" value="{!input}" />
to
<apex:inputText styleClass="form-control" id="input" value="{!input}" />

Because <apex:inputField> will bind a sobject field. But here there is no Sobject field. <!input> is not a field.
So use <apex:inputText> to bind <!input>
