Creating record through list LWC

I created record through list but problem is only Name value populated in that object the remaining fields are empty.Maping fields from Object.

import cTName from '@salesforce/schema/Coaching_Templates__c.Name';
import cTType from '@salesforce/schema/Coaching_Templates__c.Coaching_Template_Type__c';
import cTStartDate from '@salesforce/schema/Coaching_Templates__c.Start_Date__c';
import cTEndDate from '@salesforce/schema/Coaching_Templates__c.End_Date__c';
import cTActive from '@salesforce/schema/Coaching_Templates__c.Active__c';
import cTCountry from '@salesforce/schema/Coaching_Templates__c.Country__c';

The Object which hold the data

@track cTemplateList={
    Name:cTName,                
    Type:cTType,   
    Active:cTActive,
    Start_Date:cTStartDate,
    End_Date:cTEndDate,
    Country:cTCountry
          
};

Assign value to that object

  getName(event) {
     let name = event.target.value;
      this.cTemplateList.Name = name;
  }
  getType(event) {
    let type = event.target.value;
    this.cTemplateList.Type = type;
 }
 getStartDate(event) {
  let startDate = event.target.value;
  this.cTemplateList.Start_Date = startDate;
 
}
getEndDate(event) {
  let endDate = event.target.value;
  this.cTemplateList.End_Date = endDate;
  

}
getActive(event) {
  let active = event.target.checked;
  this.cTemplateList.Active = active;
}
getCountry(event) {
  let country = event.target.value;
  this.cTemplateList.Country = country;
}

Method for Insertion

 insertCTemplate(){
    console.log('ok');
    insertCTemplateMethod({cTemplateObj:this.cTemplateList})
        .then(result=>{
          
            this.cTemplateList={};
           this.cTamplateid=result.Id;
            window.console.log('after save' +  this.cTamplateid );
            
            const toastEvent = new ShowToastEvent({
              title:'Success!',
              message:'Account created successfully',
              variant:'success'
            });
            //console.log('??????' +this.accountid);
            //this.saveCoachingTemplateSecton(this.cTamplateid);
            this.dispatchEvent(toastEvent);
        })
        .catch(error=>{
           this.error=error.message;
           window.console.log(this.error);
        });
      
  }

Apex class method

 @AuraEnabled
    public static  Coaching_Templates__c insertCTemplateMethod( Coaching_Templates__c cTemplateObj){
        try {
            
                system.debug('>>>>>' + cTemplateObj );
          insert cTemplateObj;
            return cTemplateObj;
        } catch (Exception e) {
            throw new AuraHandledException(e.getMessage());
    }
 } 

Onchange event from Template

  <div class="slds-p-left_x-large slds-col slds-size_5-of-6">
                                <lightning-input type="text" label="Name" value={cTemplateList.Name} onchange={getName}></lightning-input>
                            </div>
                        </td>
                        <td>
                            <div class=" slds-p-left_x-large slds-col slds-size_5-of-6">

                            </div>
                        </td>
                    </tr>
