Reset Boxcollider around new text

I created some 3d mesh text from a prefab with an attached boxcollider.

The next text is may be larger or smaller than the original text in the prefab but the boxcollider remains the same size. This is a problem because I am using it to detect when the mouse interacts with the auto generated text.

Ordinarily I would resize the boxcollider for the text size by clicking the gear icon and selecting reset.

I would like to know if a similar operation is available to be called in c#?

 using UnityEngine;
 using System.Collections;
 
 public class GUITest : MonoBehaviour {
 
     // External Classes, GameObjects and Transforms
     public GameObject TextPrefab;
 
 
     void Start() {
                 
         Resolution[] resolutions = Screen.resolutions;
         string[] listOfResolutions = new string[resolutions.Length];
         float xPos = -8.5f;
         float yPos = 1.67014f;
         float zPos = -1.3f;
         Vector3 textPos = new Vector3(xPos,yPos,zPos);
 
 
         for (int i = 0; i < resolutions.Length; i++)
         {
             listOfResolutions[i] = resolutions[i].width + "x" + resolutions[i].height + " ";
             GameObject Text;
             Text = Instantiate(TextPrefab) as GameObject;
             Text.renderer.enabled = true;
 
             Text.transform.position = textPos;
             if ((i%6 == 0)&&(i != 0)){xPos += -2.0f; yPos = 1.67014f; zPos = -1.3f;}
             Text.GetComponent<BoxCollider>(); // not sure how to reset size to new text
             TextMesh t = Text.GetComponent<TextMesh>();
             t.text = listOfResolutions[i];
             t.transform.position = new Vector3(xPos, yPos,zPos);
             zPos += 0.5f;
             t.name = listOfResolutions[i] + "_Text";
 
         }
 
     
 
 
 
 }
 }
