I am new for LWC, I am trying to create a search bar on app page for custom object. It gives me data in console but its not showing me on screen.

What am I doing wrong in below code ?

<template>

    <lightning-card title="Search Student Here"  icon-name="standard:product"> 

    <div>

    <lightning-input type="text" value={searchString} lable="Search Student"

                    onchange={handleSearch} placeholder="Student Name">                   

    </lightning-input>

</div>

 <div if:true={searchResults}>

     <lightning-datatable data={searchResults}> 

                          columns={colums}

                          key-field="id">

     </lightning-datatable>

 </div>

</lightning-card>

</template>

******** Js.

import { LightningElement,track,wire } from 'lwc';

import getStudents from '@salesforce/apex/SearchStudents.getStudents';

const colums=[

    {lable:'id',

    fieldName:'id',

    type:'text'},

    {lable:'Student Name',

    fieldName:'Name',

    type:'text'},

];

export default class GetStudents extends LightningElement {

@track searchString;

@track colums=colums;

@track searchResults;

handleSearch(event){

 this.searchString = event.target.value;

 /* eslint-disable no-console */

console.log('this.searchString'+JSON.stringify(this.searchString));

 getStudents({studentName:this.searchString})

 .then(result=>{

     this.searchResults=result;

     console.log('this.searchResults'+JSON.stringify(this.searchResults));

 })

}

}

********* apex

public class SearchStudents {      @Auraenabled(Cacheable = true)     public static list<Student__c> getStudents(string studentName){          studentName = '%'+studentName+'%';                   list<Student__c> studentLst = [select id,Phone_Number__c,Email__c,name,School__r.name from student__c where NAME LIKE :studentName];         return studentLst;              } }
