Hello Everyone,

I need your help, I am trying to fetch data from a apex class and store it in a list. The list basically has a custom object data. now when i render it in a table and show in the html , i display the values in a table and use input fields to show. Now when i change the values from the front end it does not stores in the track variable. I know there should be some java script magic, can you help to figure out what ?

HTML:

 <template for:each={budgetData} for:item="budget"> 
                <tr key={budget.Id} class="slds-hint-parent">
                    <td >
                        <div class=" headingBG" >{budget.BG_Code__c}</div>
                    </td>
                    <td >
                        <div class=" headingBG" >{budget.BG_Name__c}</div>
                    </td>
                    <td >
                        <div class=" headingBG" >{budget.Category_Code__c}</div>
                    </td>
                    <td >
                        <div class=" headingBG" >{budget.Category_Name__c}</div>
                    </td>
                    <td >
                        
                        <div class="slds-truncate" >
    
                            <lightning-input type="text" id={budget.Id} name={budget.Upselling_Investment__c} value={budget.Upselling_Investment__c} disabled={disableFieldBudget} onchange={onchangevalues} >
                            </lightning-input>
                        </div>
                    </td>
                    <td >
                        <div class="slds-truncate" >
                            <lightning-input type="text"  value={budget.Retailer_promotion_STTI__c} disabled= {disableFieldBudget}   ></lightning-input>
                        </div>
                    </td>
                    <td >
                        <div class="slds-truncate" >
                            <lightning-input type="text"  value={budget.Consumer_promotion__c} disabled={disableFieldBudget} ></lightning-input>
                        </div>
                    </td>
                     <td >
                        <div class="slds-truncate" >
                            <lightning-input type="text"  value={budget.Brand_investment__c} disabled={disableFieldBudget} ></lightning-input>
                        </div>
                    </td>
                    <td >
                        <div class="slds-truncate" >
                            <lightning-input type="text"  value={budget.Cooperative_advertising_KAM__c} disabled={disableFieldBudget} ></lightning-input>
                        </div>
                    </td>


So when the value which comes is a list and i store it in a track. Now when i want to update i should call a onchange method may be.
